YSK: When you create an event in Google Calendar, it is attached to the time zone you are in when you create the event

Why YSK: not understanding this could cause you to miss your scheduled event.

I was traveling away from home on the west coast when I set up a doctor's appointment back home in Denver. It was for 12:30pm. After I returned home I got a reminder notice from the doctor. I double checked my calendar and was surprised to see the event scheduled for 1:30pm. Close scrutiny revealed that the event explicitly said it was Pacific Time. I changed the time zone on the event to Mountain time, and it moved to 12:30 on my calendar. Had I not received that reminder, I might have been an hour late for my appointment.

This isn't outrageously wrong behavior. If I scheduled a zoom call with someone and then traveled to a different time zone, having it adjust automatically would be the right thing.
