they can, rest assured.

during "virtual time", the tempo and beat measure at the point
where the transport has stopped remain in effect.

tick, time and frame counts continue to roll. plugins that are
not locking to transport time, ie. those that seem to interest
you the most, do not need to care at all about the distinction.

those that do lock to transport time, ie. those who record and
playback, are usually inactive while the transport is standing 
still, though they do not need to.

in fact the kind of timestamp you choose is irrelevant in this
context i think.
