I have a question regarding verification of data format before trying to insert it into a database, specifically MySQL. Is there a module that I can just use with some nifty subs that would allow me to check is_safe_date($string) prior to insertion? I've used a number of subs previously in other projects. The only thing is that they've matured as I've continued to work on projects. I am aware of Regexp::Common and DateTime::Format::MySQL. I was just wondering if anyone ever put a module together that would verify the format of data before attempting insertion. If there isn't, would this be a good project to attempt as my first published module or no?
