The root option won't actually set the time. Using clocksync instead.

Downloaded this for a Samsung Galaxy 2 Tab but it eould never sync the clock. Submitted an email to dev but never heard a word nor did I see any response on the trouble ticket list. Removed app after a couple of weeks.

I just downloaded this so,going to give it a test. Unlike others, I only require syncing once daily and/or upon boot. My device receives a restart daily anyway to free up RAM and optimize DB and cache. Plus, I like the consistency of use in the Holo-style.

Once daily?? I need it to sync every 30min... Some roms have serious clock drift and continuous sync is needed.. uninstall

Switched over from using ClockSync which went haywire on the OnePlus One with official Cyanogenmod 11S firmware. NTPSync however worked well. Please keep up the good work. Love it.

go to my phone and stay there! awesome app. careful with root apps, if you donut trust them, who knows what they are doing to your phone.... this is open source, under the GNU gpl version 3, code you can see is code you can trust! thank you dev, for making the world a better place.
