I have three IPC-HDW5231R-Z cameras all running firmware 2.460.0000000.16.R, Build Date: 2017-09-04. Two of the three seem to loose time a couple times a week for about an hour. They are all configured to use the same NTP server which is actually a load balanced IP managed by the router they sit behind. Since I control all three NTP servers being load balances I can verify they are not changing erratically since they log all time adjustments which never show more then a couple second delta. When the cameras go haywire they seem to jump 20 hours ahead. Has anyone else experienced issue with NTP on Dahua cameras.
