Hello Team,

I hope you're doing fine,

A customer wanted to implement an NTP server for his infrastructure and to integrate it with Active directory;

We created an linux ubuntu machine and configure it to sync with external NTP server, we then configured the PDC to sync with that external server, and configured the other DCs to sync with the PDC, now all machines in the domain are syncing with the DCs.

But we noticed something messed up with timezones, we are Based in morocco North africa our Time zone is Casablanca, on the servers and machines when choosing the right time zone and configuring the DST it gives the incorrect time. when i disable the daylight saving time (DST) i have the correct time.

On my personal laptop (time zone correct), the time zone for casablanca is (UTC +1) and the DST is enabled

I don't know why on my personal laptop and in the domain machines, the timezones are differents? is it the ntp server who is responsible for detecting the timezones, to know if it's UTC, UTC +1...?

Any idea how to correct it ?

    It shouldn't be the NTP server as all should be based on UTC, the client machines settings dictate any offset for time zone and or DST. You could try using a different source.
