That's okay, since it would give a different time under CGI as well.
My advice in general is that you just shouldn't use constants in Perl.
The subroutine thing is kind of a hack, and the confusing problems with
stringification are not worth the performance boost. Just use package
variables instead. This doesn't work so well for running other people's
code though.
