At that rate, a new Sync frame arrives about every 2
milliseconds. That does not leave much time for printing messages,
etc.  So, you might have to hack something yourself.

If you want to see *every* offset, then I would copy the values into a
circular buffer, and then read them out when you have enough data.

If you only want to occasionally monitor the offset, then you can poll
using the pmc client and the time_status_np request (no hacking
required).
