Field Detail

• MIN

  public static final OffsetTime MIN

  The minimum supported OffsetTime, '00:00:00+18:00'. This is the time of midnight at the start of the day in the maximum offset (larger offsets are earlier on the time-line). This combines LocalTime.MIN and ZoneOffset.MAX. This could be used by an application as a "far past" date.

• MAX

  public static final OffsetTime MAX

  The maximum supported OffsetTime, '23:59:59.999999999-18:00'. This is the time just before midnight at the end of the day in the minimum offset (larger negative offsets are later on the time-line). This combines LocalTime.MAX and ZoneOffset.MIN. This could be used by an application as a "far future" date.

Method Detail

• now

  public static OffsetTime now()

  Obtains the current time from the system clock in the default time-zone.

  This will query the system clock in the default time-zone to obtain the current time. The offset will be calculated from the time-zone in the clock.

  Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

  Returns:

  the current time using the system clock, not null

• now

  public static OffsetTime now(ZoneId zone)

  Obtains the current time from the system clock in the specified time-zone.

  This will query the system clock to obtain the current time. Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.

  Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

  Parameters:

  zone - the zone ID to use, not null

  Returns:

  the current time using the system clock, not null

• now

  public static OffsetTime now(Clock clock)

  Obtains the current time from the specified clock.

  This will query the specified clock to obtain the current time. The offset will be calculated from the time-zone in the clock.

  Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using dependency injection.

  Parameters:

  clock - the clock to use, not null

  Returns:

  the current time, not null

• of

  public static OffsetTime of(LocalTime time,
                              ZoneOffset offset)

  Obtains an instance of OffsetTime from a local time and an offset.

  Parameters:

  time - the local time, not null

  offset - the zone offset, not null

  Returns:

  the offset time, not null

• of

  public static OffsetTime of(int hour,
                              int minute,
                              int second,
                              int nanoOfSecond,
                              ZoneOffset offset)

  Obtains an instance of OffsetTime from an hour, minute, second and nanosecond.

  This creates an offset time with the four specified fields.

  This method exists primarily for writing test cases. Non test-code will typically use other methods to create an offset time. LocalTime has two additional convenience variants of the equivalent factory method taking fewer arguments. They are not provided here to reduce the footprint of the API.

  Parameters:

  hour - the hour-of-day to represent, from 0 to 23

  minute - the minute-of-hour to represent, from 0 to 59

  second - the second-of-minute to represent, from 0 to 59

  nanoOfSecond - the nano-of-second to represent, from 0 to 999,999,999

  offset - the zone offset, not null

  Returns:

  the offset time, not null

  Throws:

  DateTimeException - if the value of any field is out of range

• ofInstant

  public static OffsetTime ofInstant(Instant instant,
                                     ZoneId zone)

  Obtains an instance of OffsetTime from an Instant and zone ID.

  This creates an offset time with the same instant as that specified. Finding the offset from UTC/Greenwich is simple as there is only one valid offset for each instant.

  The date component of the instant is dropped during the conversion. This means that the conversion can never fail due to the instant being out of the valid range of dates.

  Parameters:

  instant - the instant to create the time from, not null

  zone - the time-zone, which may be an offset, not null

  Returns:

  the offset time, not null

• from

  public static OffsetTime from(TemporalAccessor temporal)

  Obtains an instance of OffsetTime from a temporal object.

  This obtains an offset time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of OffsetTime.

  The conversion extracts and combines the ZoneOffset and the LocalTime from the temporal object. Implementations are permitted to perform optimizations such as accessing those fields that are equivalent to the relevant objects.

  This method matches the signature of the functional interface TemporalQuery allowing it to be used in queries via method reference, OffsetTime::from.

  Parameters:

  temporal - the temporal object to convert, not null

  Returns:

  the offset time, not null

  Throws:

  DateTimeException - if unable to convert to an OffsetTime

• parse

  public static OffsetTime parse(CharSequence text)

  Obtains an instance of OffsetTime from a text string such as 10:15:30+01:00.

  The string must represent a valid time and is parsed using DateTimeFormatter.ISO_OFFSET_TIME.

  Parameters:

  text - the text to parse such as "10:15:30+01:00", not null

  Returns:

  the parsed local time, not null

  Throws:

  DateTimeParseException - if the text cannot be parsed

• parse

  public static OffsetTime parse(CharSequence text,
                                 DateTimeFormatter formatter)

  Obtains an instance of OffsetTime from a text string using a specific formatter.

  The text is parsed using the formatter, returning a time.

  Parameters:

  text - the text to parse, not null

  formatter - the formatter to use, not null

  Returns:

  the parsed offset time, not null

  Throws:

  DateTimeParseException - if the text cannot be parsed

• isSupported

  public boolean isSupported(TemporalField field)

  Checks if the specified field is supported.

  This checks if this time can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.

  If the field is a ChronoField then the query is implemented here. The supported fields are:

  • NANO_OF_SECOND
  • NANO_OF_DAY
  • MICRO_OF_SECOND
  • MICRO_OF_DAY
  • MILLI_OF_SECOND
  • MILLI_OF_DAY
  • SECOND_OF_MINUTE

  • HOUR_OF_AMPM
  • CLOCK_HOUR_OF_AMPM
  • HOUR_OF_DAY
  • CLOCK_HOUR_OF_DAY
  • AMPM_OF_DAY
  • OFFSET_SECONDS

  All other ChronoField instances will return false.

  If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

  Specified by:

  isSupported in interface  TemporalAccessor

  Parameters:

  field - the field to check, null returns false

  Returns:

  true if the field is supported on this time, false if not

• isSupported

  public boolean isSupported(TemporalUnit unit)

  Checks if the specified unit is supported.

  This checks if the specified unit can be added to, or subtracted from, this date-time. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.

  If the unit is a ChronoUnit then the query is implemented here. The supported units are:

  • NANOS
  • MICROS
  • MILLIS
  • SECONDS
  • MINUTES
  • HOURS
  • HALF_DAYS

  All other ChronoUnit instances will return false.

  If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.

  Specified by:

  isSupported in interface  Temporal

  Parameters:

  unit - the unit to check, null returns false

  Returns:

  true if the unit can be added/subtracted, false if not

• range

  public ValueRange range(TemporalField field)

  Gets the range of valid values for the specified field.

  The range object expresses the minimum and maximum valid values for a field. This time is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.

  If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

  If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.

  Specified by:

  range in interface  TemporalAccessor

  Parameters:

  field - the field to query the range for, not null

  Returns:

  the range of valid values for the field, not null

  Throws:

  DateTimeException - if the range for the field cannot be obtained

  UnsupportedTemporalTypeException - if the field is not supported

• get

  public int get(TemporalField field)

  Gets the value of the specified field from this time as an int.

  This queries this time for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

  If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time, except NANO_OF_DAY and MICRO_OF_DAY which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

  If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

  Specified by:

  get in interface  TemporalAccessor

  Parameters:

  field - the field to get, not null

  Returns:

  the value for the field

  Throws:

  DateTimeException - if a value for the field cannot be obtained or the value is outside the range of valid values for the field

  UnsupportedTemporalTypeException - if the field is not supported or the range of values exceeds an int

  ArithmeticException - if numeric overflow occurs

• getLong

  public long getLong(TemporalField field)

  Gets the value of the specified field from this time as a long.

  This queries this time for the value for the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

  If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

  If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

  Specified by:

  getLong in interface  TemporalAccessor

  Parameters:

  field - the field to get, not null

  Returns:

  the value for the field

  Throws:

  DateTimeException - if a value for the field cannot be obtained

  Returns:

  the zone offset, not null

• withOffsetSameLocal

  public OffsetTime withOffsetSameLocal(ZoneOffset offset)

  Returns a copy of this OffsetTime with the specified offset ensuring that the result has the same local time.

  This method returns an object with the same LocalTime and the specified ZoneOffset. No calculation is needed or performed. For example, if this time represents 10:30+02:00 and the offset specified is +03:00, then this method will return 10:30+03:00.

  To take into account the difference between the offsets, and adjust the time fields, use withOffsetSameInstant(java.time.ZoneOffset).

  This instance is immutable and unaffected by this method call.

  Parameters:

  offset - the zone offset to change to, not null

  Returns:

  an OffsetTime based on this time with the requested offset, not null

• withOffsetSameInstant

  public OffsetTime withOffsetSameInstant(ZoneOffset offset)

  Returns a copy of this OffsetTime with the specified offset ensuring that the result is at the same instant on an implied day.

  This method returns an object with the specified ZoneOffset and a LocalTime adjusted by the difference between the two offsets. This will result in the old and new objects representing the same instant an an implied day. This is useful for finding the local time in a different offset. For example, if this time represents 10:30+02:00 and the offset specified is +03:00, then this method will return 11:30+03:00.

  To change the offset without adjusting the local time use withOffsetSameLocal(java.time.ZoneOffset).

  This instance is immutable and unaffected by this method call.

  Parameters:

  offset - the zone offset to change to, not null

  Returns:

  an OffsetTime based on this time with the requested offset, not null

  Returns:

  the second-of-minute, from 0 to 59

• getNano

  public int getNano()

  Gets the nano-of-second field.

  Returns:

  the nano-of-second, from 0 to 999,999,999

• with

  public OffsetTime with(TemporalAdjuster adjuster)

  Returns an adjusted copy of this time.

  This returns an OffsetTime, based on this one, with the time adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.

  A simple adjuster might simply set the one of the fields, such as the hour field. A more complex adjuster might set the time to the last hour of the day.

  The classes LocalTime and ZoneOffset implement TemporalAdjuster, thus this method can be used to change the time or offset:

    result = offsetTime.with(time);
    result = offsetTime.with(offset);
   

  The result of this method is obtained by invoking the TemporalAdjuster.adjustInto(Temporal) method on the specified adjuster passing this as the argument.

  This instance is immutable and unaffected by this method call.

  Specified by:

  with in interface  Temporal

  Parameters:

  adjuster - the adjuster to use, not null

  Returns:

  an OffsetTime based on this with the adjustment made, not null

  Throws:

  DateTimeException - if the adjustment cannot be made

  ArithmeticException - if numeric overflow occurs

  public OffsetTime with(TemporalField field,
                         long newValue)

  Returns a copy of this time with the specified field set to a new value.

  This returns an OffsetTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the hour, minute or second. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.

  If the field is a ChronoField then the adjustment is implemented here.

  The OFFSET_SECONDS field will return a time with the specified offset. The local time is unaltered. If the new offset value is outside the valid range then a DateTimeException will be thrown.

  The other supported fields will behave as per the matching method on LocalTime.with(TemporalField, long) LocalTime}. In this case, the offset is not part of the calculation and will be unchanged.

  All other ChronoField instances will throw an UnsupportedTemporalTypeException.

  If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.

  This instance is immutable and unaffected by this method call.

  Specified by:

  with in interface  Temporal

• plus

  public OffsetTime plus(TemporalAmount amountToAdd)

  Returns a copy of this time with the specified amount added.

  This returns an OffsetTime, based on this one, with the specified amount added. The amount is typically Duration but may be any other type implementing the TemporalAmount interface.

  Adjusts the specified temporal object to have the same offset and time as this object.

  This returns a temporal object of the same observable type as the input with the offset and time changed to be the same as this.

  The adjustment is equivalent to using Temporal.with(TemporalField, long) twice, passing ChronoField.NANO_OF_DAY and ChronoField.OFFSET_SECONDS as the fields.

  In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):

     // these two lines are equivalent, but the second approach is recommended
     temporal = thisOffsetTime.adjustInto(temporal);
     temporal = temporal.with(thisOffsetTime);

• until

  public long until(Temporal endExclusive,
                    TemporalUnit unit)

  Calculates the amount of time until another time in terms of the specified unit.

  This calculates the amount of time between two OffsetTime objects in terms of a single TemporalUnit. The start and end points are this and the specified time. The result will be negative if the end is before the start. For example, the period in hours between two times can be calculated using startTime.until(endTime, HOURS).

  The Temporal passed to this method is converted to a OffsetTime using from(TemporalAccessor). If the offset differs between the two times, then the specified end time is normalized to have the same offset as this time.

  The calculation returns a whole number, representing the number of complete units between the two times. For example, the period in hours between 11:30Z and 13:29Z will only be one hour as it is one minute short of two hours.

  There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit.between(Temporal, Temporal):

     // these two lines are equivalent
     amount = start.until(end, MINUTES);
     amount = MINUTES.between(start, end);
   

  The choice should be made based on which makes the code more readable.

  The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS are supported. Other ChronoUnit values will throw an exception.

  If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.

  This instance is immutable and unaffected by this method call.

  Specified by:

  until in interface  Temporal

  Parameters:

  endExclusive - the end date, exclusive, which is converted to an OffsetTime, not null

  unit - the unit to measure the amount in, not null

  Returns:

  the amount of time between this time and the end time

  Throws:

  DateTimeException - if the amount cannot be calculated, or the end temporal cannot be converted to an OffsetTime

  UnsupportedTemporalTypeException - if the unit is not supported

  ArithmeticException - if numeric overflow occurs

• format

  public String format(DateTimeFormatter formatter)

  Formats this time using the specified formatter.

  This time will be passed to the formatter to produce a string.

  Parameters:

  formatter - the formatter to use, not null

  Returns:

  the formatted time string, not null

  Throws:

  DateTimeException - if an error occurs during printing

• atDate

  public OffsetDateTime atDate(LocalDate date)

  Combines this time with a date to create an OffsetDateTime.

  This returns an OffsetDateTime formed from this time and the specified date. All possible combinations of date and time are valid.

  Parameters:

  date - the date to combine with, not null

  Returns:

  the offset date-time formed from this time and the specified date, not null

• compareTo

  public int compareTo(OffsetTime other)

  Compares this OffsetTime to another time.

  The comparison is based first on the UTC equivalent instant, then on the local time. It is "consistent with equals", as defined by Comparable.

  For example, the following is the comparator order:

  1. 10:30+01:00
  2. 11:00+01:00
  3. 12:00+02:00
  4. 11:30+01:00
  5. 12:00+01:00
  6. 12:30+01:00

  Values #2 and #3 represent the same instant on the time-line. When two values represent the same instant, the local time is compared to distinguish them. This step is needed to make the ordering consistent with equals().

  To compare the underlying local time of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

  Specified by:

  compareTo in interface  Comparable<OffsetTime>

  Parameters:

  other - the other time to compare to, not null

  Returns:

  the comparator value, negative if less, positive if greater

  Throws:

  NullPointerException - if other is null

• isAfter

  public boolean isAfter(OffsetTime other)

  Checks if the instant of this OffsetTime is after that of the specified time applying both times to a common date.

  This method differs from the comparison in compareTo(java.time.OffsetTime) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

  Parameters:

  other - the other time to compare to, not null

  Returns:

  true if this is after the instant of the specified time

• isBefore

  public boolean isBefore(OffsetTime other)

  Checks if the instant of this OffsetTime is before that of the specified time applying both times to a common date.

  This method differs from the comparison in compareTo(java.time.OffsetTime) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

  Parameters:

  other - the other time to compare to, not null

  Returns:

  true if this is before the instant of the specified time

• isEqual

  public boolean isEqual(OffsetTime other)

  Checks if the instant of this OffsetTime is equal to that of the specified time applying both times to a common date.

  This method differs from the comparison in compareTo(java.time.OffsetTime) and equals(java.lang.Object) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

  Parameters:

  other - the other time to compare to, not null

  Returns:

  true if this is equal to the instant of the specified time

• equals

  public boolean equals(Object obj)

  Checks if this time is equal to another time.

  The comparison is based on the local-time and the offset. To compare for the same instant on the time-line, use isEqual(OffsetTime).

  Only objects of type OffsetTime are compared, other types return false. To compare the underlying local time of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

  Overrides:

  equals in class  Object

  Parameters:

  obj - the object to check, null returns false

  Returns:

  true if this is equal to the other time

  Object.hashCode(), HashMap

• hashCode

  public int hashCode()

  A hash code for this time.

  Overrides:

  hashCode in class  Object

  Returns:

  a suitable hash code

  See Also:

  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

• toString

  public String toString()

  Outputs this time as a String, such as 10:15:30+01:00.

  The output will be one of the following ISO-8601 formats:

  • HH:mmXXXXX
  • HH:mm:ssXXXXX
  • HH:mm:ss.SSSXXXXX
  • HH:mm:ss.SSSSSSXXXXX
  • HH:mm:ss.SSSSSSSSSXXXXX

  The format used will be the shortest that outputs the full value of the time where the omitted parts are implied to be zero.

  Overrides:

  toString in class  Object

  Returns:

  a string representation of this time, not null
