Current source have the issue.

Please provide any additional information below.

The problem is in it-IT.js.
It is the only .js file which uses H.mm and not H:mm.
The same for long time H.mm.ss
Corrected locally with : instead of . and it works.
I'm not an Italian specialist but I don't think they use . for date seperator.
