Yeah, enjoy mysterious crashes of some services which die
whenever system time changes rapidly, in one big step
(i.e. dovecot, TS, etc)!
Man, I sincerely hope you do *NOT* mean this seriously.
It might work on desktop but that's definitely NOT the way
time on servers should be updated! Some services are so
sensitive they crash even if you shift time 0.2s back
or forth!
I had even to include "tinker step 0" in my ntpd.conf
just because of that problem (it means ntpd will now never
adjust time by stepping, always only by slewing, which in
my case is max 0.5ms per second)...
