You could do this with datetime and timedelta from the datetime module.
>>> from datetime import datetime, timedelta
>>> fromtimetime = datetime.strptime('200903281346', '%Y%m%d%H%M')
>>> fromtimetime
datetime.datetime(2009, 3, 28, 13, 46)
>>> delta = timedelta(seconds=60)
>>> delta
datetime.timedelta(0, 60)
>>> fromtimetime + delta
datetime.datetime(2009, 3, 28, 13, 47)
>>> datetime.strftime(fromtimetime + delta, '%Y%m%d%H%M')
'200903281347'
