Sunclock is a J2ME Midlet that displays a map of the Earth and indicates the illuminated portion of the globe by drawing sunlit areas dark on light, night areas as light on dark. In addition to providing local time for the default timezone, it also displays up to four additional cities on the map with the local times also. The map updated every minute to follow the movement of the earth.

Using the Setup menu you can choose the cities according to your interest. You can give the DST rules for the chosen city. If you have internet access on your handset you should search the city using the "Search" menu and the remote service will find the proper DST rule settings for you. Otherwise you should use the provided online DST rule search service on the sunclock website. You have to specify the correct timezone values relative from GMT (for example +5.5hours will appear as 530) and the integer WGS-84 coordinates multiplied by ten (N14.7432 will be lat: 147) of the cities to display them on the map. Thus most of the current phones do not supports the timezone settings, the localtime will be calculated based on the Main City setup and the internal phone clock will be interpreted as a timezone corrected local time value according to the Main City timezone selection.
