YSK that Google Calendar adjusts to your current time zone automatically, which can cause mistakes while traveling.

For example: I was in Japan last week, 17 hours ahead of PST, my native time zone. I got a message from a friend asking to meet up the next Saturday at 10:30am. I said sure, quickly took out my phone, and plopped an event in for Saturday 10:30am. I then traveled back to the PST time zone and today, Saturday at 10:30am, I received no push notification reminder and totally missed my meeting. I looked at the calendar and saw the event was scheduled for Friday (yesterday) at 5:30pm, aka Saturday 10:30am Tokyo time.
