exslt:date-time() allows XSLT code to get the current system time. It's
the simplest function in the EXSLT date package, as it doesn't require
any support for *parsing* dates.
I raised <https://bugzilla.mozilla.org/show_bug.cgi?id=603159>, and also
attached a patch which implements this, and which works for my use case.
How do I get this into FF?
Best regards, Julian
