hello, i want to use threads in my perl program.
Why?

i want to build a method that compares a time in the future with
the current time. if both timestamps are equal i want to do
something. how could i do that.

This is what I'm doing to have a program run an update routine daily:

my $currenttime = time;

open FH, '+< update.txt' or die $!;
if ($currenttime > <FH>) {
seek FH, 0, 0;
print FH updatetime();
# run update routine
}
close FH or die $!;

sub updatetime {
# Next day at 3:47 a.m. local time
require Time::Local;
return 100000 + Time::Local::timelocal(
0,0,0,(localtime $currenttime)[3..5]);
}

Hope that helps.
