Time Zone/calendar issues

I just moved from the East Coast to the West coast. I have traveled in the past and never had an issue with the time zones or my calendar appointments. But since I've moved, my calendar is all whacked out, giving me reminders at the wrong time for events. I just changed the time zone in my calendar (I asusmed it already did that when I reset the main systems time settings) and now my phone is off worse than before!! It's driving me crazy! Please help!
