My hotel room clock just went back 1 hour. It is a Sony brand "Dream Machine" with "Auto Time Set"; I have never touched it. I actually had to google the local time to make sure the problem was the clock and not my brain -- it's the middle of the night and I just happened to wake up, somewhat in a daze.

How could this possibly have happened?! Daylight Saving has never been in June.

I have read some horror stories on FT from people who failed to receive wake up calls. A commonly proposed solution is to set the alarm. Make sure it's not the hotel clock's alarm. ^
