Examples of ZoneOffsetTransition

java.time.zone.ZoneOffsetTransition
A transition between two offsets caused by a discontinuity in the local time-line.
A transition between two offsets is normally the result of a daylight savings cutover. The discontinuity is normally a gap in spring and an overlap in autumn. {@code ZoneOffsetTransition} models the transition between the two offsets.
Gaps occur where there are local date-times that simply do not not exist. An example would be when the offset changes from {@code +03:00} to {@code +04:00}. This might be described as 'the clocks will move forward one hour tonight at 1am'.
Overlaps occur where there are local date-times that exist twice. An example would be when the offset changes from {@code +04:00} to {@code +03:00}. This might be described as 'the clocks will move back one hour tonight at 2am'. @implSpec This class is immutable and thread-safe. @since 1.8
javax.time.calendar.zone.ZoneOffsetTransition
A transition between two offsets caused by a discontinuity in the local time-line.
A transition between two offsets is normally the result of a daylight savings cutover. The discontinuity is normally a gap in spring and an overlap in autumn. ZoneOffsetTransition models the transition between the two offsets.
There are two types of transition - a gap and an overlap. Gaps occur where there are local date-times that simply do not not exist. An example would be when the offset changes from +01:00 to +02:00. Overlaps occur where there are local date-times that exist twice. An example would be when the offset changes from +02:00 to +01:00.
