On all platforms, time.time() returns the number of seconds "since the epoch". All POSIX systems agree on when "the epoch" began, but that doesn't really matter to your use case. Number of seconds since the epoch is insensitive to daylight time, time zone, leap seconds, etc. Users can nevertheless make it appear to jump (into the future or the past) by changing their system clock. If you need an absolute measure of time immune to user whims, you need to connect to special hardware, or to an external time source. -- http://mail.python.org/mailman/listinfo/python-list
