If your computer was powered off at 2:00 AM *and* your hardware clock
is set to local time instead of UTC, then it would have missed the change.
The computer now thinks it is on PDT, but on boot-up it synced to the
hardware clock which was still on PST.
That's why it's usually better to have the hardware clock set to UTC. Unless
you are dual booting to Windows, then the advantage/disadvantage balance
tilts toward having the hardware clock set to local time.
