About this app

This app displays the exact time.

Birthday, daylight saving time, or New Year's Eve, it can't get more accurate and simple than this.

You can also keep the time on your mobile phone or tablet accurate with the atomic clock. However, setting the time requires root privileges.

Tap on the clock to hide the controls.

Features:

Display current time
Supports landscape and portrait orientations
Display milliseconds
24-hour and AM/PM modes
Display refresh rate can be adjusted, lower values conserve your battery
Automatically set the exact time + date for root users. The update interval is adjustable.
To get the most accurate time, it's best to use the app in a stable Wi-Fi or good 3G/LTE reception. In areas with poor reception, the time may be slightly inaccurate.

Technical information:
The time is synchronized via NTP servers and therefore requires the internet. The app uses your mobile phone only as a reference clock; the accurate time comes from the NTP server.

Great App for when you really want to know PRECISELY what time it is, to set your watch to the exact second, for instance. Simple yet very useful.
