ZonedDateTime.truncatedTo介绍

[英]Returns a copy of this ZonedDateTime with the time truncated.

Truncation returns a copy of the original date-time with fields smaller than the specified unit set to zero. For example, truncating with the ChronoUnit#MINUTES unit will set the second-of-minute and nano-of-second field to zero.

The unit must have a TemporalUnit#getDuration()that divides into the length of a standard day without remainder. This includes all supplied time units on ChronoUnit and ChronoUnit#DAYS. Other units throw an exception.

This operates on the local time-line, LocalDateTime#truncatedTo(TemporalUnit)the underlying local date-time. This is then converted back to a ZonedDateTime, using the zone ID to obtain the offset.

When converting back to ZonedDateTime, if the local date-time is in an overlap, then the offset will be retained if possible, otherwise the earlier offset will be used. If in a gap, the local date-time will be adjusted forward by the length of the gap.

This instance is immutable and unaffected by this method call.
[中]返回此ZoneDateTime的副本，时间被截断。
截断返回原始日期时间的副本，其中字段小于指定的单位，设置为零。例如，使用ChronoUnit#MINUTES单位进行截断会将秒数和秒数字段设置为零。
该单元必须有一个临时单元#getDuration（），它可以划分为一个标准日的长度，没有余数。这包括ChronoUnit和ChronoUnit#天上提供的所有时间单位。其他单位会抛出一个例外。
它在本地时间线LocalDateTime#truncatedTo（TemporalUnit）基础本地日期时间上运行。然后将其转换回ZoneDateTime，使用分区ID获取偏移量。
当转换回ZoneDateTime时，如果本地日期时间重叠，那么如果可能，将保留偏移量，否则将使用较早的偏移量。如果存在间隙，本地日期时间将根据间隙的长度向前调整。
此实例是不可变的，不受此方法调用的影响。
