I updated the firmware on all 11 of my cameras - Some a V2, some are V3. After updating the firmware, I went through the various settings… on one of the v2’s and one of the v3’s the “Sync Time” setting will not work. I get a “Network has timed out” message after about 30-45 seconds. The rest of the cameras Were able to sync time without a problem.
I just posted about my local cams being an hour and 6 minutes off after a power outage. I was able to reset the time on a V2 which had not been updated but not a V3 which had been updated.
