Multiple International Date formats - in a single web application

Has anyone dealt with multiple date formats in a single application based on a user specified location?

The application will be hosted on a single server, with multiple people logging in. I'd like them to see the information in their format, rather than a preset or server format.

Any suggestions, comments, actual experience would be helpful.

A comment is made at the end of the following video about localizing date fields. I'm not sure what is involved on the server-side; I haven't quite figured out what the rules are in Alpha when it comes to data type conversion when going from the string data in Xbasic that I get back from the client. I find myself constantly having to slap in "convert_type" function calls in xbasic. I would be wary of dates and I'm so glad I don't have to deal with that problem.

We tried it with an international application with mild success, but not completely. We provide each customer with a choice of date format, recorded in a customer preferences table, then make sure that's used in the date controls. If you only have a couple of date controls and you're not doing much with them, it'll probably be fine.

But we have a lot of other requirements that just didn't play well at all. For instance, the customer may have a dd/mm/yyyy format, but then as a standard we display dd-MON-yy (e.g. 10-OCT-16) and it just didn't all work.

I definitely need to revisit it sometime, but after all the work to fix the problems this all created, I just left it for a (long) while.
