Field Summary

Fields
Modifier and Type	Field	Description
`static TimeMeter`	`SYSTEM_MILLISECONDS`	The implementation of `TimeMeter` which works around `System.currentTimeMillis()`
`static TimeMeter`	`SYSTEM_NANOTIME`	The implementation of `TimeMeter` which works around `System.nanoTime()`

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`long`	`currentTimeNanos()`	Returns current time in nanosecond precision, but not necessarily nanosecond resolution.
`boolean`	`isWallClockBased()`	Returns `true` if implementation of clock behaves the similar way as `System.currentTimeMillis()`, in other words if implementation can be used as wall clock.
