The difference you are seeing is purely related to how you are printing it; executing a "print" statement as opposed to the interactive interpreter printing a value. Notice: Roy-Smiths-MacBook-Pro:play$ python Python 2.5.1 (r251:54863, Feb 6 2009, 19:02:12) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import time >>> print time.time() 1248484949.75 >>> time.time() 1248484957.151274 and further notice: >>> x = time.time() >>> str(x) '1248485028.58' >>> repr(x) '1248485028.5814769' Keep in mind that while a float may have a large apparent precision, there's no promise that the actual value returned by the OS has that much precision. You should be fine if all you're looking for is ms, but I wouldn't count on much more than that. -- http://mail.python.org/mailman/listinfo/python-list
