After googling a bit better then yesterday, i've done:

 root at clerk:~# lxc-info -n 100 -c lxc.cap.drop
 lxc.cap.drop = mac_admin
 mac_override
 sys_time
 sys_module
 sys_rawio

and so i've added to /etc/pve/lxc/100.conf:

 lxc.cap.drop:
 lxc.cap.drop: mac_admin mac_override sys_module sys_rawio

and now:

 root at clerk:~# lxc-info -n 100 -c lxc.cap.drop
 lxc.cap.drop = mac_admin
 mac_override
 sys_module
 sys_rawio

So now i can run a NTP on my container, providing probably that is the
only container with cap 'sys_time' enabled.


Clearly i can run ntp on the hostm, or in a VM, but an AD DC mandate
the presence of a ntp server, and probably having an NTP server that,
if needed, cannot write to HWclock, could be a source of troubles...
