are), and the extraneous calls to tzset(3) should be removed.
I haven't done this yet, as I don't want to change this code as
little as possible when introducing the time.tzset and time.tzsetwall
methods. This should simply be a method of doing the following once,
at the top of this function and removing the call to tzset() from
time_tzset():

tzset()

And I'm lazy and hate C so nyer.
