That's great.  One thing though...

You are running split() on the same string three times and running
strip on the same time tuple each time through the loop.  I know that
you shouldn't optimize before testing for bottlenecks but this is just
egrecious as well as making it more difficult to read.  Consider this.

year = str(time_tuple[0]) # strip() not really needed here
mon = str(time_tuple[1])
day = str(time_tuple[2])

for nnn in [x.split() for x in hhh]:
    if nnn[2] == mon and nnn[3] = day and nnn[4] = year:

If strip() were needed you could leave off the argument.  The default
is to strip all whitespace from both ends.  In fact, read up on locales
to see why it is a good idea to omit the argument.
