Exact Time is a simple but very useful app that always tells you the exact time in your time zone.
It connects to the internet (data connection is required) to a special kind of server, called an NTP server. This kind of server always replies with a message containing the exact time. The App will then display the received time and sync with the server from time to time to ensure accuracy.
Exact Time can also run in Fullscreen Mode in order to always keep the time displayed on the screen (by default lock screen is disabled when fullscreen is activated). Fullscreen Mode can be customized by changing background and text colors.
At the moment “Live Tiles” cannot be updated frequently enough to display actual time on them. Also, current Windows Phone OS version does not allow apps to set system time. As soon as those cool features are unlocked Exact Time will be updated to support them!
Exact Time is absolutely FREE, you can download it from here
