I have had some situations where I replaced a router running 12.2 (or 12.2T) with a router running 12.3 (or 12.3T) and have not had difficulties in getting NTP working on them. I am not aware of any change that would produce the symptoms that you describe.
Perhaps we can look at it step by step and find where (and then why) NTP is not working. First, is your internet router able to sync with its source?
It might help if you would post some details of how NTP is configured.

i have the "ntp server 188.8.131.52" which is the internet router, when you do a "sh ntp assoc" you see 184.108.40.206 is configured but it does not sync( no *) I'll have a further look.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
