I'm not sure if I understand your problem correctly. Do you want to extract the date from the filename? In that case you should be aware of a problem at the change of years. Consider e.g. 1224 (24th December 2002) is before 0101 (1st January 2003) but just looking at 1224 and 0101 you would normally judge the other way round, as you should assume they are in the same year.

On the other hand - if you know that these files will be changed and updated once a week - you should be able to guess the change of year correctly.

Anyway, take a look at Time::Local which allows to convert a date into epoch seconds. If you do that for both dates (guessing the year correctly) then you should be able to just compare the epoch seconds and tell if you need to update.
