[Datetime-SIG] Allow numerical arguments for timezones

[Guido van Rossum]

My guess is that the OP is parsing dates that have a numerical TZ offset
(like most date formats found in internet protocols like http or email
headers). But there's really no substitute for just calling

    datetime(....., tzinfo=timezone(timedelta(hours=......)))
