True enough as long as the machine is up across the transition.  If the 
machine is down across the transition and your hardware clock is local 
time, you'll need to set the new correct local time before booting.  With 
a UTC hardware clock, that step is never necessary.  (If you run NTP, I'm 
not sure if the system clock will be reset immediately on boot or if it 
will go through a catch-up phase.)
