Modifying DateTime in Device Settings

I'm developing a mobile app (using Outsystems 11) where users can record time-in and time-out (client call) offline.

the problem is when the user modify his/her device date time settings before recording time-in and time-out (cheating).

Is there a way I can avoid this?

Hi Clint Menguito,

I think the only way is asking to server time, but if you want to do it offline... I don't know, sorry.
