Hello everybody! I'm trying to produce a timestamp (system time) in windows (Python 2.7) with resolution equal to or better than microseconds. Calling time.time() repeatedly in a loop it appears it only updates in approximately 0.01 second increments. Using datetime.datetime.today() seems to show similar results. If the Timer function is not precise enough, you can use Windows API calls to the system high–resolution timer. The high–resolution timer is built into most, but not all CPUs. The high–resolution timer has two important pieces of information: the number of elapsed counts and the number of counts per second.
