A time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 10:15:30+01:00. 
 OffsetTime is an immutable date-time object that represents a time, often viewed as hour-minute-second-offset. This class stores all time fields, to a precision of nanoseconds, as well as a zone offset. For example, the value "13:45:30.123456789+02:00" can be stored in an OffsetTime. 

This is a value-based class; use of identity-sensitive operations (including reference equality (==), identity hash code, or synchronization) on instances of OffsetTime may have unpredictable results and should be avoided. The equals method should be used for comparisons. 
Implementation Requirements:
This class is immutable and thread-safe.
Since:1.8

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:

Returns a copy of this OffsetTime with the time truncated. 
 Truncation returns a copy of the original time with fields smaller than the specified unit set to zero. For example, truncating with the minutes unit will set the second-of-minute and nano-of-second field to zero. 
 The unit must have a duration that divides into the length of a standard day without remainder. This includes all supplied time units on ChronoUnit and DAYS. Other units throw an exception. 

The offset does not affect the calculation and will be the same in the result.

Adjusts the specified temporal object to have the same offset and time

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 amount 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 amount 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.

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. 

  2. 11:00+01:00
    3. 

  3. 12:00+02:00
    4. 

  4. 11:30+01:00
    5. 

  5. 12:00+01:00
    6. 

  6. 12:30+01:00
    7. 

 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. 
Params:
  • other –  the other time to compare to, not null
Returns:the comparator value, negative if less, positive if greater
