My HTC One still uses years old timezone information for its clock widget. I fixed the main clock by setting timezone to a different timezone that I'm actually in, but the clock widget is still off by one hour. It's extremely infuriating. Apparently you can't update timezone information in Android unless you have root, which is completely idiotic.
