And how do the phones get configured to NTP?

The time/date update is totally dependant on the phone.  It has  
always been the case that the phone requests the time from CM at the  
end of a call.  In later loads the phones also request the time once  
per day from CM and this time request is spread around.   Before this  
change you could have a phone that didn't make any calls for a while  
and the time could get off by a good bit due to natural clock  
drift.    This only applies to the "older" phones (7940, 60, etc) as  
the newer phones will talk directly to an NTP server (these phones  
were the ones affected by the DST changes).

Yea, the time updates on phone are wonky at times. Sometimes they  
take after a call, sometimes it takes a few hours, to quite a few  
hours, sometimes need to reset phone, etc.  Ryan R had mentioned in  
earlier post that the phone gets the time updated when a call is hung  
up, but I have seen that not work sometimes also.

in the lab the phones set to CMLOCAL did not change on a 3.33  
setup.    If we turned off the dst adjustment and then changed the  
time, we sometimes got the update.
