Caught out by daylight saving :-(

I had the following bit of code which was working fine until we went
into Daylight saving this weekend, now the result is an hour out.
timeString = "20090330 15:45:23"
timeFormat = '%Y-%m-%d %H:%M:%S'
modificationTime = datetime.datetime.utcfromtimestamp( time.mktime
( time.strptime( timeString, timeFormat ) ) )
minutesToAdvance = datetime.timedelta( minutes=5 )
modificationTime = modificationTime + minutesToAdvance
datetimeString = str ( modificationTime ).replace( ' ', 'T' )
The expected result should be:
datetimeString = "20090330T15:50:23"
But instead I get:
datetimeString = "20090330T14:50:23"
I believe it is going wrong at either the mktime() or utcfromtimestamp
What is the correct way to fix this compensating for daylight saving
