    Represent a timezone with a fixed offset from UTC and no adjustment for
    DST.

    >>> FixedOffset(4,0)
    <UTC+04:00>
    >>> FixedOffset(-4,0)
    <UTC-04:00>
    >>> FixedOffset(4,30)
    <UTC+04:30>

    >>> tz = FixedOffset(-5,0)
    >>> tz.dst(None)
    datetime.timedelta(0)

    The class tries to do the right thing with the sign
    of the time zone offset:

    >>> FixedOffset(-9,30)
    <UTC-09:30>
    >>> FixedOffset(-9,-30)
    Traceback (most recent call last):
    ...
    ValueError: minutes must not be negative

    Offsets must thus be normalized so that the minute value is positive:

    >>> FixedOffset(-8,30)
    <UTC-08:30>
