Stopwatch

A simple facility to measure time intervals with microsecond resolution.

#include <icy/datetime.h>

class Stopwatch

Defined in src/base/include/icy/datetime.h:1733

A simple facility to measure time intervals with microsecond resolution.

The Stopwatch uses the current system time, so if the system time changes the measured time will be incorrect.
