本文整理了Java中java.time.ZonedDateTime.minus()方法的一些代码示例，展示了ZonedDateTime.minus()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.minus()方法的具体详情如下：
包路径：java.time.ZonedDateTime
类名称：ZonedDateTime
方法名：minus

ZonedDateTime.minus介绍

[英]Returns a copy of this date-time with the specified period subtracted.

This method returns a new date-time based on this date-time with the specified period subtracted. This can be used to subtract any period that is defined by a unit, for example to subtract years, months or days. The unit is responsible for the details of the calculation, including the resolution of any edge cases in the calculation.

The calculation for date and time units differ.

Date units operate on the local time-line. The period is first subtracted from the local date-time, then converted back to a zoned date-time using the zone ID. The conversion uses #ofLocal(LocalDateTime,ZoneId,ZoneOffset)with the offset before the subtraction.

Time units operate on the instant time-line. The period is first subtracted from the local date-time, then converted back to a zoned date-time using the zone ID. The conversion uses #ofInstant(LocalDateTime,ZoneOffset,ZoneId)with the offset before the subtraction.

This instance is immutable and unaffected by this method call.
[中]返回此日期时间的副本，并减去指定的期间。
此方法基于此日期时间返回一个新的日期时间，并减去指定的期间。这可以用来减去单位定义的任何期间，例如减去年、月或日。该部门负责计算的细节，包括计算中任何边缘情况的解决方案。
日期和时间单位的计算方法不同。
日期单位在当地时间线上运行。首先从本地日期时间中减去时段，然后使用区域ID将其转换回分区日期时间。转换使用带有减法前偏移量的#of local（LocalDateTime，ZoneId，ZoneOffset）。
时间单位在即时时间线上运行。首先从本地日期时间中减去时段，然后使用区域ID转换回分区日期时间。转换使用#of Instant（LocalDateTime、ZoneOffset、ZoneId）和减法前的偏移量。
此实例是不可变的，不受此方法调用的影响。
