Detailed Description

Utility class that measures the elapsed time.

cpp3ds::Clock is a lightweight class for measuring time.

Its provides the most precise time that the underlying OS can achieve (generally microseconds or nanoseconds). It also ensures monotonicity, which means that the returned time can never go backward, even if the system time is changed.

Usage example:

...
Time time1 = clock.getElapsedTime();
...
Time time2 = clock.restart();

The cpp3ds::Time value returned by the clock can then be converted to a number of seconds, milliseconds or even microseconds.

This function returns the time elapsed since the last call to restart() (or the construction of the instance if restart() has not been called).

Returns
Time elapsed
Time cpp3ds::Clock::restart ( )

Restart the clock.

This function puts the time counter back to zero. It also returns the time elapsed since the clock was started.
