Patching pytz with import hook to have usable generic timezones
"""
Import hook extending pytz package with usable, generic timezones:
GMT-14 up to GMT+12.
Note that pytz already has Etc/GMT+X timezones, but
(quoting Wikipedia):
"In order to conform with the POSIX style, those zones beginning with "Etc/GMT"
have their sign reversed from what most people expect. In this style,
zones west of GMT have a positive sign and those east have a negative sign."
