I know that ntp uses UTC and the clients have to manage any DST and timezone differences on their own.
The problem I have is that several noname ip cameras have a non-working DST implementation, and randomly add/subtract hours, resulting in almost always incorrect time. All of the cams allow to sync with ntp servers, though. So I thought one way around the problem would be to serve the local time including DST (if applicable) as "UTC" to the cameras, and turn off any timezone/DST settings. Is this possible (without messing up the linux system)?
The CentOS system is running in a VM and is synching its time from another ntp host on the network. No other systems sync with this system, so the ntpd time would be only for the ip cameras. The CentOS system itself has to continue working with the correct time.
In case this is a really bad idea, I'm also open to other suggestions ;)
