Google Calendar Timezones
This is the first time I've used Google Calendar and traveled between time zones. When I loaded it up, it asked me if I want to change to Hong Kong Time. I clicked yes, thinking it would just change the alerts and such.
Nope. It actually remembers what your events are in UTC time, and displays them in Hong Kong Time. I only noticed when Mythbusters was suddenly at 10;00 on Thursdays...
Once again in so many days, good job Google.
