Hi is there any way to get real time..

I’m going to build app which have license validation.. for the very first time the internet connection is must.. after noo need of internet. We storing expiry date in encrypted way locally. With that we compare local date and time and getting to validation expired or not.

*Issue*: if user changing their time in setting everywhere time getting changed.. so they bypassing the validation.

Is any work arround or idea to achieve validation properly without internet:smiling_face_with_tear: even they change the time in their device..!! Any idea should he appreciated. 

I faced a similar problem, and I just did a check if the automatic time setting is enabled, so that will make insure always local time is correct
here is a question on stackoverflow about how to achieve that

another trick some vendors use is to store the last known time you checked something, then if you end up checking _before_ that last known time, you know that the clock can't be trusted
