init(self, spec=None, flip=False)
(Constructor)

source code

Create a time zone instance with a fixed offset from UTC.

Parameters:

spec - Specifies the offset. Can be an integer counting minutes east of UTC, the value None (equal to 0 minutes east), or a string that conform to the ISO8601 time zone sequence (Z, or [+-]HH:MM).
flip - If False (default), no adaptation is done. If True, the time zone offset is negated, resulting in the conversion from localtime to UTC rather than the default of UTC to localtime.
