[Bug 12339] We should mention that UAs may use a different clock than the wall clock for defining the rate of time in the media timeline, specifically so that they are allowed to use the soundcard clock to ensure reliable audio playback.

I don't think that the HTML5 spec. requires that the time-of-day clock be used
for clocking media out, only that as the TOD clock progresses, playback also
progresses.  I agree, it's normal to use the audio clock as the base clock for
media, not time-of-day.  This is a media-specific playout issue that we
shouldn't get into.  (People writing streaming specs have to; we don't.)
