Interface ApiClock (2.1.2)

An interface for getting the current value of a high-resolution time source, in nanoseconds.

Clocks other than NanoClock are typically used only for testing.

This interface is required in addition to Java 8's Clock, because nanoTime is required to compare values with io.grpc.CallOptions.getDeadlineNanoTime().

Returns the current value of this clock's high-resolution time source, in milliseconds.

Returns the current value of this clock's high-resolution time source, in nanoseconds.
