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

The datetime module documentation contains an example tzinfo class that represents a fixed offset.

ZERO = timedelta(0)

# A class building tzinfo objects for fixed-offset time zones.
# Note that FixedOffset(0, "UTC") is a different way to build a
# UTC tzinfo object.

class FixedOffset(tzinfo):
    """Fixed offset in minutes east from UTC."""

    def __init__(self, offset, name):
        self.__offset = timedelta(minutes = offset)
        self.__name = name

    def utcoffset(self, dt):
        return self.__offset

    def tzname(self, dt):
        return self.__name

    def dst(self, dt):
        return ZERO

Since Python 3.2 it is no longer necessary to provide this code, as datetime.timezone and datetime.timezone.utc are included in the datetime module and should be used instead.
