This is pretty much related to CGI-stuff, but then again, i'm making it with Perl, so guess that justifies writing this here :)

In standard cookie the expiry-date format is like this: "Sat, 20 Feb 2010 01:31:52 GMT". I would need to create a script that updates this timestamp with each login with 1 hour addon, so the expiry date is allways 1 hour ahead the time user last received a cookie from this script. This way i try to ensure that the problem with shared computers don't come up with login. At least it's controlled in some way, if user forgets to logout.

My question is, how should i test that timestamp and make sure of that 1 hour addon to be made correctly? Should i just test every segment of it, like if hours are now 23, make sure next is 0 and so on? I obviously have to take in consideration leap year as well. I'm sure there's nothing but tons of already made modules for this kind of date manipulation, but i cannot install those to this server, so i need to write my own handler.

I am aware how to split and read that timestamp with regex, so no problem there.
