At the hackathon today I worked on my first inPulse app: a world clock. It seemed pretty popular so I decided to release it right away. Any lingering bugs can be fixed later. The app includes an animated spinning globe with realistic shading of day and night according to the time and season. You can scroll through all the time zones using the watch button.

It has instructions for changing the hard coded local timezone offset (which you will need to do if you are in a timezone other than Pacific Daylight) and some important limitations info (notably, daylight savings time is not supported).
