Interesting problem that has hit a great many of us over time. The question is - Is the data unique enough to eliminate "bad data".
valid formats per your post
date range Jan 01 1900 through Jan 01 2005 (assume this will be used for a while). What data can we eliminate as invalid.
take data in couplets.
So having wandered about a bit, my conclusion IMHO is that this type of "edit" returns no value in a large percent of the time because while a format may be found as having violated none of the rules, we still have no idea what date was intended.
Valid and usable data are two different animals, just because the data passes all the tests we can think of, doesn't mean it is fit for the use we want to put it to.
