This same issue also exists between Ubuntu and Debian, causing unsolvable time differences
between the two on a dual booting machine. I didn't know that timedatectl was simply being
ignored in Ubuntu! 

What I would want would be a hardware clock that the OS can't change, set to local time in 
all cases. I never use network time updating due to the issue of having a requirement for machines
that do not reveal their IP address to anything I do not deliberately connect to.  Unfortunately 
Tor requires knowing the time zone to work so as to avoid time based attacks. Thankfully it does 
NOT require network time!
