Yes.

Measuring kernel execution time using events [1] will however miraculously 
make your teeth brighter, save a few baby dolphins and contribute 5 Hungarian 
Forint towards world peace.

start = Event()
stop = Event()
start.record()
do_timed_stuff()
stop.record()
do_other_untimed_stuff()
stop.synchronize()
time_in_seconds = stop.time_since(start)*1e-3
