public interface NanoTimer
Interface to specify custom implementation of precise timer.
- Dawid Kurzyniec
Returns the current value of the most precise available system timer,
- Returns the current value of the most precise available system timer,
in nanoseconds. This method can only be used to measure elapsed time and
is not related to any other notion of system or wall-clock time. The
value returned represents nanoseconds since some fixed but arbitrary
time(perhaps in the future, so values may be negative). This method
provides nanosecond precision, but not necessarily nanosecond accuracy.
No guarantees are made about how frequently values change. Differences
in successive calls that span greater than approximately 292 years
(263 nanoseconds) will not accurately compute elapsed time due to
- The current value of the system timer, in nanoseconds.
