Georg Brandl <georg@python.org> added the comment: It seems to me that the quoted function from bzr def local_time_offset(t=None): """Return offset of local zone from GMT, either at present or at time t.""" # python2.3 localtime() can't take None if t is None: t = time.time() if time.localtime(t).tm_isdst and time.daylight: return -time.altzone else: return -time.timezone would be very helpful to add to the `time` module docs as an example. I have to agree with the OP that the current state of the docs is not as clear as it could be. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue7229> _______________________________________
