简介

The HRTime extension implements a high resolution StopWatch class. It uses the best possible APIs on different platforms which brings resolution up to nanoseconds. It also makes possible to implement a custom stopwatch using low level ticks delivered by the underlaying APIs.

Note: As of PHP 7.3.0 the related function hrtime() is part of the core.
