I'm using Class::DBI to interface with my MySQL db. Unfortunately, I don't get the fine-grained control of the queries I'm used to. I've had to create a trigger to update a "created_on" column with the current date/time because it's not possible to use MySQL's NOW() function.

Now I need to retrieve all rows that have been added in the past x days. I have used Class::DBI like so to create a new constructor that allows me to search based on date:

Company->add_constructor(get_recent => 'created_on > ?');

Now, I just need to figure out how to pass the new constructor a date in the correct format. I can get a date in the correct format using Time::Piece (which is what I'm using in the trigger to create the column in the first place). However, I need to take this date and subtract x days from it, so I could get all records added in the past 5 days or something. Any help would be greatly appreciated.

I searched CPAN and found tons of date modules, but I'm having a problem finding ones that implement the interval subtraction I need. Date::Calc doesn't seem to have it. I ran a supersearch as well and didn't turn up much.
