I'm confused. How does the way that you store dates internally have anything to do with date parsing? If you are accepting dates from users, then you still have to normalize then to unix timestamps.
That also doesn't cover things like:
* Take this date and convert it into a week represented by the last Sunday of the week (i.e. 20110410 represents 20110403-20110409).
