block the manual change of date and time

[Carlos Andre]

I am developing application for access control and cannot allow user to change date and time of android device manually. Is there a way to block the manual change of date and time?

[SteveJG]

There is probably NOT a way to "to block the manual change of date and time" using the Android's Settings.  Device manual Settings override all code in the app.  

Why do you want to block a manual change?

don't get the date and time from the device, get it form a server instead...

you can do this using the web component and a date time API of your choice

also there are extensions available, for example
