After updating an IP 500 V2 to 8.1.43 the 54xx phones time is acting strange. It is correct at 10, 11, 12 o'clock, but when it rolls to 1, 2, 3, etc, the first 1 stays. So at 1pm it reads 11:00, and 4pm it reads 14:00. If you pick up the handset and put it back down, the screen refreshes and the 1 goes again, then time is correctly displayed. It isn't military time, just that the 1 doesn't disappear when it rolls to the single digit hours. Anyone seen this? Any ideas?
