    Unless you query an external time server, you will never know whether the given system time is accurate. This would require an internet connection however. I don't honestly think someone will change their system clock, which in turn will screw up a lot of other applications, to simply circumvent your application expiry logic.

    You can use your database for this purpose. In this case your database will say your program what date is to pick and if you want to make some change it will be done in the database neither in the system nor in the program.

    Hey, here’s the code I’m sharing to get in the date and time just check this :

    Code:
    import java.util.Date;
    import java.text.DateFormat;
    import java.text.SimpleDateFormat;
    import java.util.Calendar;
    
    public class GetCurrentDateTime {
      public static void main(String[] args) {
    
           DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
           //get current date time with Date()
           Date date = new Date();
           System.out.println(dateFormat.format(date));
          
      }
    }
