Re: calculate the time taken to run a script

Take the time at the start and end of the program and subtract the first from the second.

You may want to look at Time::HiRes if you want sub-second accuracy.

Perl already keeps track of start time for you in $^T, so unless you're doing something really funky, you can just subtract that from the current time to get elapsed time. `END { my $elapsed_seconds = time - $^T; # Do something with $elapsed_seconds # e.g., print qq(<!-- Script took ${elapsed_seconds}s to run -->); }` [download] --k.
