Thanks for the detailed explanation, but I didn't create the script this is
in. Someone else did over a year ago and I wanted to get it y2k. I have
already read up on localtime and understood that, but since I don't know
perl, I didn't know how to continue. Anthony was kind enough to give me
the solution.
All is well now.
