I have 2 models of phones on the system 7906 and 7940. The 7906 is showing the wrong time whereas the 7940 is correct. the 7906 is one hour behind. I have the network locale set in telephony service as UK, but on the settings of the phone it says it is using the built in network locale which is set to US. The firmware for the phone is 8.2 Sr1, which is the reccomended. Is there a way of forcing the phone to use the system locale as opposed to the phones inbuilt one?
