TOR Time Sync in a personal OS

i tried to install tor and arm on my simple OS .
It runs correctly but arm provides me the alert about time sync, how can I implement whonix network time sync ?
Or there are other methods ?
is it a big problem the time sync on my personal OS ? However i have UTC time .

For Whonix users, official advice for host’s:

There are “upstream projects”, which likely(!) work on [most?] Debian based operating systems [or even other Linux’s?], they likely work or would only need little effort to make them work, but this is [still] unsupported by the Whonix team:

What do you mean by unsupported?
