I recently got a new 8 channel Hikvision PoE NvR from Nelly's, and 2 of my four cameras are one hour behind. I added pool.ntp.org to the NTP setting, and two of my cameras are still 1 hour behind. I then tried enabling DST, but then my two cameras that are behind end up becoming correct, and my two cameras that were correct before end up being ahead 1 hour. I then tried using manual time sync, and it had the same effect as enabling DST. No matter what I try, all four of my cameras will not display the same time. I can't think of anything else to try. Has anyone else seen this problem?
