Use server-based time instead of user’s system time

[delta6626]

Currently, the app uses the user’s system time to control access, which can be easily manipulated by changing the device clock. To improve reliability and prevent this, it would be great to fetch the current time from a trusted API like WorldTimeAPI or TimeAPI. This way, the app can verify time based on a server source rather than local time.

Let me know what you think or if you want me to start working on a PR for this.
Thanks!
