    What happens if the user alters the date on their device?

      The timestamp is based on the device. However, some of the security data comes from the Witness validation server and others from the platform (Google Play Integrity/Apple App Attest). Altering the date/time on the device would conflict with that information, and possibly fail the device validation. One of the key criteria for using the app is it will only run on a device that passes validation from the platform. So rooted devices can't run the app, as they can't pass validation.
