We got burned by Verizon on the time change. We always use out cell phones as our alarm clocks. Last night right before I went to bed I checked the Verizon webite to confirm they had a handle on the earlier switch to DST. No problem it claimed, so we set the alarm and went to sleep. It goes off this morning at 5:30, I confirm the time on the phone when I turn it off, then 15 minutes later my wife got a call from the hospital telling her she's late to work. By the time I got her to the hospital the phone was reading the correct time, so sometime between 5:30 and 6:00 it figured out how to fix itself, just a little too late for us.
