Method Detail

now

public long now()

Specified by:

now in interface MonotonicClock

See Also:

Provides a monotonic time that can be compared with any other such value produced by the same clock since the application started only; these times cannot be persisted or serialized to other nodes. Nanosecond precision.

error

public long error()

Specified by:

error in interface MonotonicClock

Returns:

nanoseconds of potential error

translate
