I just arrived at the firstleg of my trip. I turned on my phone to call and say I'd arrived. The phone automatically reset its clok to local time. (good)

I looked at my calendar for my nexy flight, and the time was changed! My entire calendar was adjusted by the difference in time zones. I've manually reset (all?) of my upcoming flights, I think.

1) How could I have prevented this?!!

2) Will MfE adjust all my times on my Outlook calendar in California? Over what time span?

HELP!!
