Hi Kamil,

Thanks for the patch.

What other kind of timestamps there can be? All drivers (at least those not
mem-to-mem) that do obtain timestamps using system clock use monotonic ones.

I'd think that there should no longer be any drivers using the UNKNOWN
timestamp type: UNKNOWN is either from monotonic or realtime clock, and we
just replaced all of them with the monotonic ones. No driver uses realtime
timestamps anymore.

How about making MONOTONIC timestamps default instead, or at least assigning
all drivers something else than UNKNOWN?
