We have received reports from 2 separate people indicating the time did not change correctly on CISCO phone Models 7940, 7960, 7961 and others. The readers that notified us indicating that the phones had been updated per recommendations of the vendors. One of our readers indicated the CISCO TAC is unreachable due to volume so my guess is that Shawn and Peter aren't the only ones that have noticed the problem.
Shawn indicated that it appears to be a Java update problem.
Thanks to Shawn and Peter for providing us with the information.
