Humbly submitted.

Fun activity: add groupings to parse bits (words) of it out if you're so inclined. (See RFC 4122 for the bits' meanings. Also likely better done through unpack, but I warned you this was a fun activity.)
($time_low) = $uuid =~ m/^([[:xdigit:]]{8})-(?:[[:xdigit:]]{4}-){3}[[: +xdigit:]]{12}$/

[zentara]: Strange, on clicking a link in a node, I am taken to that node, but my votes and login are lost. Should I post a Permonks Discussion?
[choroba]: that just means someone used a wrong link format
[choroba]: msg them or consider to fix
[zentara]: Gratias
[LanX]: pm != tk ;)
[Corion]: zentara: Most likely they used something like [http://www. node=123456] instead of [id://123456], which uses whatever domain you're visiting from
[LanX]: hmm... Actually this could be used for a phishing exploit ...
[LanX]: ... well like always :)
