Thanks for all your input.
I checked out the perldocs of CGI.pm and I found out I've been doing a lot of extra work. I should probably check out other people's code more often.

About that time format, it's translated from dutch and I normally don't use capitals in the days.

I'll pay more attention to the formatting, use perltidy, be strict and pray to the almighty camel I will become a better monk in the near future ;)
