From the Python documentation. https://docs.python.org/2/library/time.html#time.strptime
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).
Which basically says that time.strptime()
will only recognize timezones that are listed in time.tzname
Hope this helps
