This function returns a millisecond time.
The return is relative to an arbitrary time in the past, and not related to a date time or time stamp. Therefore not subject to clock drift. The primary use is for measuring the elapsed time.
If lipstick-ECS runs in browser, present() calls performance.now() actually. If in node, present() calls process.hrtime().
