Was it hours off?  If yes, it's probably you haven't configured timezone in the device pool.

You need to set the date/time group setting under the Device Pool. You may need to create a new Date/Time group for the site, System>Date/Time Group.

You may also want to check Date/Time group. Not all time zones are compatible with all phone models. I know this was a common issue with certain phones and CUCM 7.1(3). Not sure if it impacts 7.1(2) as I skipped that version for all of my customers.

In any case, you may have a date/time group or Device Pool configuration oversight.

HTH.
