DST not handled correctly

suds.sax.date.Timezone uses time.timezone as the offset from UTC. However documentation of time.timezone states:

The offset of the local (non-DST) timezone, in seconds west of UTC (negative in most of Western Europe, positive in the US, zero in the UK).

So using time.timezone that way only works half the year. The result is that when a datetime is used in a SOAP call, the value in the request contains the correctly formatted local time followed by an incorrect specification of which time zone was used. For example 2013-06-26 16:05:58.887627 CEST was rendered in the SOAP request as 2013-06-26T16:05:58.887627+01:00, which is incorrect as CEST is +02:00.
