Methods Summary
static long	currentThreadTimeMicro() Returns microseconds running in the current thread. return elapsed microseconds in the thread hide return System.currentTimeMillis() * 1000;
static long	currentThreadTimeMillis() Returns milliseconds running in the current thread. return elapsed milliseconds in the thread return System.currentTimeMillis();
static long	currentTimeMicro() Returns current wall time in microseconds. return elapsed microseconds in wall time hide return elapsedRealtime() * 1000;
static long	elapsedRealtime() Returns milliseconds since boot, including time spent in sleep. return elapsed milliseconds since boot. return System.currentTimeMillis() - sBootTime;
static long	elapsedRealtimeNanos() Returns nanoseconds since boot, including time spent in sleep. return elapsed nanoseconds since boot. return System.nanoTime() - sBootTimeNano;
static long	uptimeMillis() Returns milliseconds since boot, not counting time spent in deep sleep. Note: This value may get reset occasionally (before it would otherwise wrap around). return milliseconds of non-sleep uptime since boot. /*package*/ return System.currentTimeMillis() - sBootTime;
