Re: Figuring out Date Format

The trouble with "unknown" date formats is that you have to start with some assumptions, and then hope they wil hold true.

Your first two examples, 01012008 and 01/01/2008 do not raise any questions.
.
But what would be the case if you were presented with 06122008 or 06/12/2008 - is this date in December or in June?

Looking at your 3rd example, 20080101, what would we do if presented with 20082009 - is this 20th August 2009 or 20th September 2008?

Again, what year, month and day does 07/08/09 if we do not know the date format?.

I know this is not the answer you wanted to hear ...

Subject: Figuring out Date Format

Is there an API or a BIF that I can pass in an unknown date format and get
back a date format I can expect? I am seeing how difficult it might be to
allow a user to enter in a date how they want. (ex. '01012008' '01/01/2008'
'20080101') and return *ISO or something else. I could write a subprocedure,
but I thought I would see if there is something out there that would either
make the code easier or eliminate my needing it.
