I have googled, but I can find no advice to prevent user change system date/time in android.

We are developing an Enterprise Application, we would like to prevent the user of the device to be able to set time settings. In other words, we want to set a policy which defines, that user cant change date and time in android device. Are there any recommendations to do this? Thanks.

Here is a third alternative that should significantly save on battery life:

Register a BroadCast Receiver for when the time gets changed by the user. Then disable the app until the device time is checked against network-time or server-time.

Those Broadcast Receivers exist. I just checked now with this app called Internal Broadcast Monitor I just found on Google Play.

Here is the interesting part below where I changed both the time and the date:
