[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.

Just be careful to assume that the sound card actually has a monotonically
increasing global clock which can be queried independently of any audio
streams. In actuality the sound card has a ring buffer and it's (hopefully)
possible to query approximately which sample in that ring buffer is in the DAC
right now.

So, just be a bit vague and it'll be fine.
