I recently took over a website with a MySQL database already in place. In it, it uses a 'unix_date' category to create dates like '1068938100' and that's the only date object I have available.

Obviously, that won't look good on an online calendar. Noone will understand it.

So how can I use MX to possibly convert it over to something better looking like November 10, 2003 or just 11/10 for example? Is that possible?

Try here:

I think its from_unixtime
