How to set UTC offset for datetime?

Question

My Python-based web server needs to perform some date manipulation using the client\'s timezone, represented by its UTC offset. How do I construct a datetime object with the spe

Answer 1

As an aside, Python 3 (since v3.2) now has a timezone class that does this:

from datetime import datetime, timezone, timedelta

# offset is in seconds
utc_offset = lambda offset: timezone(timedelta(seconds=offset))

datetime(*args, tzinfo=utc_offset(x))

However, note that "objects of this class cannot be used to represent timezone information in the locations where different offsets are used in different days of the year or where historical changes have been made to civil time." This is generally true of any time zone conversion relying strictly on UTC offset.
