public enum TimeUnit
extends Enum<TimeUnit>
TimeUnit represents time durations at a given unit of granularity and provides utility methods to convert across units, and to perform timing and delay operations in these units.TimeUnit does not maintain time information, but only helps organize and use time representations that may be maintained separately across various contexts.TimeUnit 表示给定单元粒度的时间段，并提供实用程序方法来跨单元转换，以及在这些单元中执行计时和延迟操作。TimeUnit 不维护时间信息，但只帮助组织和使用可能在不同上下文中单独维护的时间表示。微秒为千分之一毫秒，
毫秒为千分之一秒，
一分钟为六十秒，
一小时为六十分钟，
一天为二十四小时。
A TimeUnit is mainly used to inform time-based methods how a given timing parameter should be interpreted. For example, the following code will timeout in 50 milliseconds if the lock is not available:
时间单元主要用于通知基于时间的方法如何解释给定的时间参数。例如，如果锁不可用，下面的代码将在50毫秒内超时:
public enum Lock lock = ...;
if (lock.tryLock(50L, TimeUnit.MILLISECONDS)) ...
while this code will timeout in 50 seconds:
而这段代码将在50秒内超时:
Lock lock = ...;
if (lock.tryLock(50L, TimeUnit.SECONDS)) ...
Note however, that there is no guarantee that a particular timeout implementation will be able to notice the passage of time at the same granularity as the given TimeUnit.
但是请注意，并不能保证特定的超时实现能够注意到与给定时间单位相同粒度的时间流逝。
