本文整理了Java中java.time.ZonedDateTime.minusHours()方法的一些代码示例，展示了ZonedDateTime.minusHours()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZonedDateTime.minusHours()方法的具体详情如下：
包路径：java.time.ZonedDateTime
类名称：ZonedDateTime
方法名：minusHours

ZonedDateTime.minusHours介绍

[英]Returns a copy of this ZonedDateTime with the specified period in hours subtracted.

This operates on the instant time-line, such that subtracting one hour will always be a duration of one hour earlier. This may cause the local date-time to change by an amount other than one hour. Note that this is a different approach to that used by days, months and years, thus subtracting one day is not the same as adding 24 hours.

For example, consider a time-zone where the spring DST cutover means that the local times 01:00 to 01:59 occur twice changing from offset +02:00 to +01:00.

  • Subtracting one hour from 02:30+01:00 will result in 01:30+02:00
  • Subtracting one hour from 01:30+01:00 will result in 01:30+02:00
  • Subtracting one hour from 01:30+02:00 will result in 00:30+01:00
  • Subtracting three hours from 02:30+01:00 will result in 00:30+02:00

This instance is immutable and unaffected by this method call.
[中]返回此ZoneDateTime的副本，并减去指定的时间段（以小时为单位）。
这是在即时时间线上进行的，因此减去一个小时的持续时间总是提前一个小时。这可能会导致本地日期时间的更改量超过一小时。请注意，这与按天、月和年使用的方法不同，因此减去一天与加24小时并不相同。
例如，考虑一个时区，其中Spring DST切换意味着本地时间01:00到01:59发生两次从偏移+02:00到+01:00的变化。
*从02:30+01:00减去一小时将得到01:30+02:00
*从01:30+01:00减去一小时将得到01:30+02:00
*从01:30+02:00减去一小时将得到00:30+01:00
*从02:30+01:00减去三小时将得到00:30+02:00
此实例是不可变的，不受此方法调用的影响。
