I asked about this on the JACK list just now and was recommended to 
bring the question here instead.  So here we are.

If I'm running JACK with output to my first (and only) PCM device, and 
I have a JACK client running that also sets up an ALSA sequencer 
queue with its timer set to the ALSA PCM 0-0-0 playback timer,  
should I expect the ALSA queue's current time and the number of 
frames processed by the JACK client to correspond?

(Ignoring rounding error and any delays in startup time or 
measurement: I simply mean that they shouldn't drift.)

I would expect them to remain in sync, and on both of my machines here 
they do, but I have a report from someone experiencing a quite 
considerable drift -- the JACK frame count ends up over a second and 
a half ahead of the ALSA timer over a ten minute period without 
xruns.  How could that happen?
