So, is the issue that time is incorrect or the fomat is incorrect?
Is the time/date group assigned to the proper device pool?
Are you using device mobility by any chance and phone is in roaming mode?
can you provide screen shots of your date/time group, device pool, the device and View Current Device Mobility Settings link on the device?
39XX phones are SIP phones - correct?
You need to configure 'Phone NTP Reference' first and then assign it to the 'Date/Time Group'. And as you already said, the 'Date/Time Group' need to be set on the 'Device Pool'.
It should help.
I hope this isnt a dumb question but can the SIP phones IP reach the defined NTP server Ip address.
Please rate useful posts.
Not a dumb question (was the only thing I hadn't tested due to time), but I've just tested it and it can be reached. Heres some screen shots of one of the affected 3905s (attached)
Despite the date format at bottom the phone is still displaying wrong format as MM/DD/YYYY!
According to the 3905 Admin guide the Date&Time format is hard coded in the
related Locale files. It doesn't look like this is a configurable feature
User locale associated with the phone user. Identifies a set of detailed information to support users, including language, font, date and time formatting, and alphanumeric keyboard text information.
