WorldTime 8

This app was a candidate in the Apptivate.MS semi-finals. See how it did among the other candidates in the Interest group.

WorldTime 8 is an application that shows what time it is in different locations across the world. It stands out from the crowd by featuring a day-night sun map (terminator line) that does not use data services to create the map. Choose from over 500 cities to show the time (with daylight savings) and sunrise/sunset times.


  • Day-night sun map (terminator line) calculated and rendered locally
  • Pin your favorite cities to the start screen on a wide or square tile and always see the time. (requires lock screen access)
  • Updated Daylight savings start and end dates.

Coming soon:

  • Meeting planner!!!

  • Analog clock option;

  • Multiple world maps to choose from;

  • Update DST dates from live service (if user chooses to). Periodic app updates will ensure that the DST are always up to date

The Day-night sun map is interesting. Does the yellow dot in the first screenshot represent the current location? Is Internet connectivity required for the app? If so, are you using any API?
Software Developer Nov 21 '12 at 18:51
I believe that is the zenith, the sun is directly overhead/impacting this point. I have similar representation in my WP7 app Sun clock…. But this World Clock image is nicer and it has more features, nice work!

@mvark, Software Developer is right. The yellow dot represents the sun. To answer your other question, the app does not use internet connectivity for building the map, getting DST or city information. The only reason it requires internet connectivity is for the Ads.
