No, the apps I'm familiar with (a DB and a JVM) need a timestamp

accurate (e.g. we've been talking about gettimeofday generically,
but these apps would use clock_gettime for nsec resolution),
monotonically increasing, and work properly across a VM
migration.  The timestamps are taken up to a 100K/sec or
more so the apps need to ensure they are using the fastest
mechanism available that meets those requirements.

Out of interest, do you know (and can you relate) why those apps need 100k/sec monotonically increasing timestamps?
