Method Details

now

public static NanoTimestamp now()

Returns a timestamp representing the current time.

never

public static NanoTimestamp never()

Returns a timestamp from ~146 years ago, for representing the time of events that have not occurred.

See Also:

• isNever()

isNever

public boolean isNever()

Returns true if this timestamp was created by never(), otherwise false.

compareTo

public int compareTo(NanoTimestamp o)

Specified by:

compareTo in interface Comparable<NanoTimestamp>

elapsed

public Duration elapsed()

Returns the time elapsed since this timestamp was created.

NOTE: If this timestamp is never(), the returned value will be at least 146 years.

See Also:

• isNever()

hasElapsed

public boolean hasElapsed(Duration d)

Returns true if the time elapsed since this timestamp was created is greater than or equal to the given duration, otherwise false.

If this timestamp is never(), this method returns true for all "reasonable" durations (less than ~146 years).

minus

public Duration minus(NanoTimestamp rhs)
