It arrived late for some reason.

You can do what you want much more simply using datetime.strptime()
and strftime():
In [2]: from datetime import datetime, timedelta
In [3]: format = '%Y%m%d_%H%M%S'
In [8]: d=datetime.strptime('20080321_113405', format)
In [10]: d
Out[10]: datetime.datetime(2008, 3, 21, 11, 34, 5)
In [13]: d += timedelta(seconds=200)
In [14]: d
Out[14]: datetime.datetime(2008, 3, 21, 11, 37, 25)
In [15]: d.strftime(format)
Out[15]: '20080321_113725'
