since Python is an object-based language, clearly you could make your
counter into a self-contained object instead of writing endless amounts
of code and wasting CPU cycles by storing what's really a *single* state
in a whole bunch of separate variables.
in your specific example, you can even use an existing object:
t = datetime.datetime.now()
t += datetime.timedelta(milliseconds=msec)
print t.timetuple() # get the contents
if you're doing this so much that it's worth streamlining the timedelta
addition, you can wrap the datetime instance in a trivial class, and do
t += 1500 # milliseconds
when you need to increment the counter.

that could of course be because when he was free to use whatever tool he
wanted, he always used a crowbar, because he hadn't really gotten around
to read that "tool kit for dummies" book.
