A simple, yet well done utility, letting you pick any spot on the Earth's surface and then showing sunrise and sunset times (in local times), along with how long the sun will be up in the day (hey, useful for farmers!) In fact, the UI is done well enough that I can't help but wish for an extra 'weather summary' graphic too. And with an option to use absolute (GMT/UTC) times instead...

From the Store description:

Suntime - Sunrise & Sunset. Shows the time for sunrise and sunset for a specific date and position. Search for a specific location, choose from map, or let the application track your current location!

Here's the utility in action:

The hamburger menu just brings up the map, which can be panned and zoomed as needed. Note again that all times are done 'as if local', which probably makes sense. I'm still wishing for a 'world' option that lets you see everything in absolute time, mind you!

You can grab this here in the Store for your Windows 10 phone, tablet or laptop.
