in thread calculate the time taken to run a script

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 -->);
}
