The old app is in perl.
In particular I want to create the feed so I can include the <lastbuilddate> in the channel data. The RFC-822 date for the feed will only be used for that particular function.
I'm thinking my options are to recode the application and all date references to make the dates permanently compliant (can't do that, since I don't have the code skills to rewrite the app), or b) convert the existing date format on the fly, but not store it anywhere, or c) use a system date which is created each time the feed is created.
Obviously the latter is most optimal, I'm thinking.
Anyway, any ideas on a solution that requires minimal coding, no changes to the native app date format, and that which a non-programmer can figure out?
