LocalDateTime.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.

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。这可用于减去单位定义的任何期间，例如减去年、月或日。该单位负责计算的细节，包括计算中任何边缘情况的解决方案。
此实例是不可变的，不受此方法调用的影响。
