I have 5 hikvision cameras, and none of them I have the correct time. I live in a GMT+1 zone and currently we have the summer time (1 hour more)
When I syncronize manually with my PC, after a while it goes bananas and shows 30 minutes less on one camera, on another camera it shows 1 hour less.
When I use the option NTP (I use an Italian server, ntp1.inrim.it, but tried others too) it gives one hour LESS, even if I correctly put GMT+1
so I try to fool him saying I am in Athens (GMT+2) but is not working, still shows 1 hour less
What a crappy software
