The withEarlierOffsetAtOverlap() method of a ZonedDateTime class is used to return a copy of this ZonedDateTime object after changing the zone offset to the earlier of the two valid offsets at a local time-line overlap. The overlap happens when Daylight saving time finishes and one hour is returned to timeline. Due to this there are two valid offsets for the local date-time and calling withEarlierOffsetAtOverlap method will return a ZonedDateTime with the earlier of the two zones. If this method is called when it is not an overlap, this is returned. This instance is immutable and unaffected by this method call.
public ZonedDateTime withEarlierOffsetAtOverlap()
Parameters: This method accepts no parameters.
Return value: This method returns a ZonedDateTime based on this date-time with the earlier offset.
Below programs illustrate the withEarlierOffsetAtOverlap() method:
