services - Is there NTP like time syncing for non rooted phone?

I need from time to time sync clock on android phone from internet. Traditional way on non mobile devices is to use NTP servers and daemon. To run NTP daemon and automatically set time on android phone one requirement is to have a root access. Is there really any similar solution for non-rooted phone?

Answer

Unfortunately, you really need root for this.

From ClockSync, Google themselves have mentioned this:

Hi, it is by design that applications can not change the time. There are many subtle aspects of security that can rely on the current time, such as certificate expiration, license management, etc. We do not want to allow third party applications to globally disrupt the system in this way.
