Comment 2 for bug 441223

I checked in svn revision #2743. This now enables the Entity Time.
The client sends out both: jabber:iq:time, and the newer urn:xmpp:time,
however, in case both return an answer, only the result of urn:xmpp:time is shown.
When urn:xmpp:time returns an error, the result of jabber:iq:time is shown

This also may need some more testing. Tested between two OpenBSD boxes,
having the timezone set to the same, and with differerent time zones.
