datetime - When will the java date collapse?

Question

AFAIK java stores dates in long variables as milliseconds. Consequently someday there will be no value (cause long has a maximum) which will correspond to the time of that instant. Do you know when it will happen?

Answer 1

It's easy enough to find out:

public class Test {
    public static void main(String[] args) {
        System.out.println(new java.util.Date(Long.MAX_VALUE));
    }
}

Gives output (on my box):

Sun Aug 17 07:12:55 GMT 292278994

You may need to subtract a bit from Long.MAX_VALUE to cope with your time zone overflowing the range of long, but it will give a reasonable ballpark :)
