Same. My phone automatically changes, and I'll manually change my watch, but when I travel, I leave my laptop in my home time zone. Part of it is I just can't be bothered, and part of it is I want an easy way to know what time it is at home without having to fiddle with a world clock.

Time zone is purely a displayed time consideration. I'm not bothered that the display time on my computer is different from the time zone I'm actually in.
