21st Century Earth Clock
EarthClock shows the correct time of day for any location in the world. It's a great utility for any traveler or anyone with international business. Just point to a city on the world map to see the time there. EarthClock is accurate for every time zone, and properly accounts for daylight savings time.

In addition, EarthClock draws Earth's night shadow and changes in real time. As the real Earth turns, EarthClock's map accurately reflects the planet's light and dark sides. When you see the shadow advance across your city on the map, look outside and you'll be witnessing sunset. EarthClock accurate accounts for the tilt of the planet, so the shape and position of the shadow also changes with the seasons. It's really fascinating to watch.
