If that's what you're interested in, time granularity is nanoseconds
for each and every scheduler.

Look at xen/common/schedule.c, xen/common/sched_credit.c,
xen/common/sched_credit2.c and xen/common/sched_rt.c, and see how they
all use the NOW() macro for reading time.

Then go checking how NOW() is defined.
