Method Detail

now

public long now()

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()

Returns:

nanoseconds of potential error

isAfter

public boolean isAfter(long instant)

isAfter

public boolean isAfter(long now,
                       long instant)
