I was of a completely different mindset than most folks, I guess. My agency is way too cheap to ever send me to a different timezone, so I was thinking about vacation, during which times my whole calendar could start breakdancing of its own accord and I could care less
As far as self-updating phones, someone I was traveling with to a different time zone proudly waved their phone under my nose, demonstrating that their phone had automatically adjusted. I'm assuming that theirs was a GSM phone, and mine (not being GSM) will probably never do so, as djdanska pointed out earlier.
