Time on phones is off by 2 hours

We have Poly Vxx350 phones and they are all syncing with RingCentral. Problem is the time is 2 hours ahead. It is set to the correct time zone (Pacific) in Phone System-Auto Receptionist-General Settings-Regional Settings. Is there somewhere else that I should be checking? Also, the time stamps in Reports-Call logs are also 2 hours ahead.
