Actually, it expects a struct_time, but will work with a tuple.  The
easiest way to build a struct_time from your string would be using

time.strptime(), as suggested by Vlastimil.

The other problem is one of timezone. I would assume that svn would be
expecting all times to be in UTC, so to convert from struct_time in UTC
to seconds since epoch, you'd use calendar.timegm()
<http://docs.python.org/2/library/calendar.html#calendar.timegm>    See
the chart on http://docs.python.org/2/library/time
