The worst offender is probably AudioContext, where you can get
the current time thus:
{{{
var audioContext = new AudioContext();
audioContext.currentTime;
}}}
Similarly, HTMLVideoElement.currentTime, HTMLAudioElement.currentTime, and
CanvasCaptureMediaStream.currentTime can be used as a time source with
resolution better than 10 ms.
