... and if you're wondering why your OFT-ANSWERED QUESTION has garnered so many downvotes, I would guess that many (like mine) were for your apparent failure to read the introductory material about the Monastery (links will be found in the right sidebar, in all likelihood) or even start with such advice as can be found in How do I post a question effectively?.

On the other hand, don't worry about the downvotes. And Welcome!

But do make your visits more productive by learning about and using the resources here. For just one example, entering the words convert and time in the search box (in the *usually* blue "Perl Monks" title-bar near the top of the page) would have shown you links to some of the many times your question has been asked and answered in the past.
