I was pretty surprised that the Windows Phone inbuilt alarm clock doesn't allow you to set alarm time for events happening in different time zones, e.g. I am in Singapore and I want to set an alarm for a match happening in Australia. I don't want to do the time math myself and just want to able to set the time zone for the alarm as Australia.

To solve this small issue, I have developed an app called World Alarm Clock.
