paul that is awesome.... so much better than what i did which was lamo
brute force method. I formmatted and reformatted my input data and
stuffed it in a HUGE dictionary.... it was stupid and kludgy.... i hope
to study all these approaches and learn something.... here's what i
came up with ... with my pea sized brain...

#!/usr/bin/env python

# New in version 2.3 is the 'datetime' module (see standard library
reference)
# http://www.python.org/doc/lib/module-datetime.html

import datetime

mykeys = inseqs.keys()      # first make a copy of the keys
mykeys.sort()               # now sort that copy in place

for key in mykeys:
event = inseqs[key]
print '\n','Item #', key, event
