If you set the clock to local time, and you have no network
connection, then you _will_ have to manually change the clock in the
computer manually after the switchover occurs.

The auto-adjust only works if you have the clock set to UTC, have your
timezone configured correctly, and let the C libs do the necessary math
conversion when you request time.

The reason you see auto-adjust with the clock set to local time is very
likely the result of your ntpdate cron job.  So yes, you get automatic
changing, but because of external network accesses.

If you used utc, and a properly configured timezone, you'd still see
local time for all your clock/date outputs, but you would get the
auto-switch over even without any external network connection.

Yes, you do, but only because of this extra setup on your part.

If you used UTC as the system time, and told the C libraries your
proper timezone, you would not need the extra setup to get DST changes
to happen.

You'd only need the extra setup to keep your clock from drifting too
far away from reality.
