Just off the cuff: If your system is set to use UTC, local time and changes

NTP-aware systems shouldn't have any problem - correct? (I figure that the
time servers will change on the new days.)
I checked ntp.org and the timeservers site - didn't mention anything about
the new dates.
If the Linux system is running at the time of the change, it will do the
Right Thing whether set to local or UTC, whether ntp or not.
If the Linux system is not running at the time of the change, it will do
the Right Thing if it is UTC. If it is local, it will always assume the
hwclock has the correct local time on boot.
If you dual-boot Windows, what happens depends on which system is running
at the change time and which system is booted next and whether you use UTC
(which requires living with GMT as your Windows time zone) or local time
(which requires paying attention).
I'm not sure about NTP systems, but there is some delay between the
setting of the system clock from the hwclock at startup and the startup of
ntpd. So there may be a short (or longer if you use NetworkManager) delay
between startup and clock correction.
