title: Android: Actual Date and Device Date
body: <p>This is my first time to ask here on Stackoverflow and I am apparently having a hard time on this one. How could I identify if the user changed the device's date in order to activate a date-based code actions?</p>
  
  <p>I really need to compare the actual date and device date without internet connection.</p>
  
  <p>For example:
  When I click this button, it would only open in August 29. Changing the date would allow me to access the function of the button.</p>
