LocalTime atOffset() method in Java with Examples

The atOffset() method of a LocalTime class is used to combine this time with an offset object to create an OffsetTime object. All possible combinations of time and offset are valid.

Syntax:

public OffsetTime atOffset(ZoneOffset offset)

Parameters: This method accepts a single parameter offset which is the offset to combine with LocalTime Object, not null.

Return Value: This method returns the offset time formed from this time and the specified offset, not null.

Below programs illustrate the atOffset() method:

        // create a LocalTime Object
        LocalTime time
            = LocalTime.parse("16:12:49");
  
        // create a ZoneOffset object
        // with 7200 sec means 2 hours
        ZoneOffset offset
            = ZoneOffset.ofTotalSeconds(7200);
  
        // apply atOffset()
        OffsetTime offsettime
            = time.atOffset(offset);
  
        // print LocalDateTime
        System.out.println("Offset Time:"
                           + offsettime.toString());
    }
}
