  4. Q: What is UTC?
    A: "Coordinated Universal Time or Universal Time Coordinated (UTC): A coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM), which forms the basis of a coordinated dissemination of standard frequencies and time signals.

We currently list some of the maps and non-US cities in GMT time because we don't have time zone information for the whole world yet.

  5. Q: How can I find Sunrise / Sunset information for other dates?
    A: We use a mathematical formula to calculate the sunrise/sunset in the US. This formula takes into consideration lat/lon and timezone of the city that you are looking at. Each zipcode may have a different lat/lon, so the sunrise/sunset times may vary slightly. If you are looking for sunrise/sunset data in the future or past, try this web site:
