AT%CTVZ=1 just enables the unsolicited result code. There is no way to 
actually _query_ the time from the network. It depends on the operator whether 
it sends it to you or not. It also depends on the modem whether it can 
understand the network time report or not. The unsolicited result code can 
occur at any time, e.g. during cell handover or registration.

You probably need to look for it (read: log data) for a couple of hours or 
days to spot it. In germany you will not get it at all. In fact whereever I 
have been since 2006 I never have seen one. Then again, I've not been in the 
US since 2002.
