I had a similar issue some time ago. Some clients would sync with DCs some other didn’t.

I recently had issues also with bookworm and NTP (bookwork installing ntpsec). I decided to move all DCs to chrony, worked perfectly, and all member servers to systemd-timesyncd with a minimal config from samba wiki that just *works*

Re. Windows clients, I have not seen may Local CMOS clocks lately after these changes.

This question may have been asked before, but how many DCs do you run, and do all have the same config for time (ntp, chrony) ?

What’s the output of  w32tm /monitor in the clients ? What’s the output of w32tm /query /status ?

On a good client (syncing with a DC) what is the logon server ? ( Run set l )
On a bad client (not syncing with a DC) what is the logon server ? Is there a pattern ?

Regards, LP
