The timezone in ‘t2’ will only be understood subject to the caveat: Support for the %Z directive is based on the values contained in tzname and whether daylight is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones). <URL:https://docs.python.org/3/library/time.html#time.strptime> So you'll need to see what your Python implementation supports (see ‘time.tzname’). The support for time zones is always a pain, because they *change* rapidly, arbitrarily, and with very little warning. Because of this, the Python standard library does not attempt to contain a timezone database, since it would almost immediately be out of date. Install the ‘pytz’ package to get the latest released timezone database supported in Python <URL:https://pypi.python.org/pypi/pytz>. -- \ “It is better to have loft and lost than to never have loft at | `\ all.” —Groucho Marx | _o__) | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
