The best world clock, including twilight!

A beautiful world clock, showing the world as it is between day and night. See the lights show through at dusk and fade away at dawn – something you would see in real life, but is missing from other world clocks.

You can also zoom in to the map to get a better view of that area of the map. Try zooming into the area around dawn or dusk to see the transition occur in real time.

In addition, a dynamic time display with your local date and time, as you have them defined on your device, are displayed below the map. You can also customize the appearance of the clock to display only date, hours, and minutes if desired.

A lot of machine-assisted translations have been added as well, please comment if the translations can be improved!

not too bad...

About the graphics: Yeah, they are not the greatest, but YES YOU CAN zoom in by using the 2 finger pinch/shrink. Maybe the developer could use the higher res pic from nasa. My main graphics complaint is with the night shading. In this app, the Antarctic region shows night as bands stepping from black to gray, but once you hit the countries, it's a gradual diffusion from black to gray and you don't get a sharp day/night line.

Accuracy: Perfect. I don't know if I can post a website, so google "day and night clock" and click on the first link. You will see that what you see on the web is what you see with the app. On the website, if you change the time and date to match that of the screenshot of this app uploaded in itunes, and set the timezone to CA, you'll get a perfect match. So, this app does what it says it does.

When the phone is locked: the app still runs in the background. When unlocked the app will update the day/night image in about 10 secs. This app seems to run in real time.

Annoyance: The scrolling seconds hand.

Using this app versus making the website I mentioned a webapp? Well, the webapp will give you MUCH better graphics, but this app has room for improvements and works offline.

Doesn’t do very much at all.

Decent graphics, and you are able to zoom into any location easily, but you are not able to change the rate of time. Imagine zooming into a location and watching the seconds tick by while waiting for sunset. Who’s going to sit for 15 minutes while the horizon imperceptibly moves one second at a time.

Good - needs improvement

Should be able to advance clock manually by hour/day. Needs an option to turn off clock at bottom of screen- would like choice of different style digits as well.
