Represents a fixed timezone offset (without daylight saving time).
@ivar name: A L{str} giving the name of this timezone; the name just
includes how much time this offset represents.
@ivar offset: A L{TimeDelta} giving the amount of time this timezone is
offset.

Construct a L{FixedOffsetTimeZone} from an offset described by sign
('+' or '-'), hours, and minutes.
@note: For protocol compatibility with AMP, this method never uses 'Z'
@param sign: A string describing the positive or negative-ness of the
offset.
@param hours: The number of hours in the offset.
@param minutes: The number of minutes in the offset
@return: A time zone with the given offset, and a name describing the
offset.
