[SOLVED] Help with RTC

[RoffDaniel]

Hello everyone. I really need help. A virtual machine with a domain controller on Windows Server 2022 has been created. If you use "Use local time for RTC", the time is synchronized, but over time it begins to lag behind. If you set "No", the time is obviously not synchronized and the local CMOS time is set. But another problem is with the "No" option. I can't install an external NTP server. He writes "Local CMOS Clock" everywhere. Does it have anything to do with each other?

Thank you!

Can you install NTP (Meinberg is a good choice) on the VM?

Have you enabled time sync in windows?

On Windows? Or other local NTP server?

Of course! But it doesn't synchronize for me, as I can't change it to any external RTC server, as long as only Local CMOS Clock, and writes "Synchronization is not complete, as there is no time data available."...

Is your proxmox server set to the same TZ that you're in? and --localtime set?

On the domain controller VM.

I think there might be some confusion here. Windows (and most other OS) does not keep time using the RTC. It only uses that to initialize at startup.

For a normal Windows install you want the RTC enabled and set to local time. Then you _also_ should set up some kind of NTP sync inside the VM. You do not need to and should not disable the RTC to set up NTP sync.

My negligence was all to blame. I created a PDC Group Policy and forgot about it. The issue has been resolved. Thank you all very much!

Glad to hear you were able to sort the problem out.
