包路径:org.threeten.bp.zone.ZoneOffsetTransition
类名称:ZoneOffsetTransition
[英]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.
Gaps occur where there are local date-times that simply do not not exist. An example would be when the offset changes from +03:00 to +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 +04:00 to +03:00. This might be described as 'the clocks will move back one hour tonight at 2am'.
This class is immutable and thread-safe.
[中]由当地时间线的不连续性引起的两个偏移之间的过渡。
两个偏移之间的过渡通常是夏令时切换的结果。这种不连续性通常是春季的一个间隙,秋季的一个重叠。ZoneOffsetTransition为两个偏移之间的过渡建模。
当本地日期时间根本不存在时,就会出现间隔。例如,偏移从+03:00更改为+04:00。这可能被描述为“时钟将在今晚凌晨1点向前移动一小时”。
如果存在两次本地日期时间,则会发生重叠。例如,偏移从+04:00更改为+03:00。这可以被描述为“今晚凌晨2点钟会向后拨一小时”。
####实施者规范
这个类是不可变的,是线程安全的。
