The last (additional) element is the time zone offset in seconds, except if the timezone was specified as -0000. In that case the last element is None. This indicates a UTC timestamp that explicitly declaims knowledge of the source timezone, as opposed to a +0000 timestamp that indicates the source timezone really was UTC.
