接口 Clock

public interface Clock

A timing source that can be used to access the current wall time as well as a high resolution monotonic time to measuring elapsed times. Most of the time the SYSTEM implementation that calls the builtin java methods is probably the right one to use. Other implementations would typically only get used for unit tests or other cases where precise control of the clock is needed.

wallTime

long wallTime()

Current wall time in milliseconds since the epoch. Typically equivalent to System.currentTimeMillis.

返回:

wallTime

monotonicTime

long monotonicTime()

Current time from a monotonic clock source. The value is only meaningful when compared with another snapshot to determine the elapsed time for an operation. The difference between two samples will have a unit of nanoseconds. The returned value is typically equivalent to System.nanoTime.

返回:
