@GwtCompatible public abstract class Ticker extends Object
A time source; returns a time value representing the number of nanoseconds elapsed since some fixed but arbitrary point in time. Note that most users should use Stopwatch instead of interacting with this class directly.

Warning: this interface can only be used to measure elapsed time, not wall time.
