In amdcal/samples/common/Timer.cpp (AMD streaming SDK 1.2beta)
Timing is calculated using following statement:
(i64)s.tv_sec * 1000 + (i64)s.tv_usec/1000
This causes measured time round to 1ms (losing precision)
It is not a big deal. But it may affect time measurement when the actual time is around few ms.
