I know there's good alternatives such as the GAGE timer, but I've just taught myself Java(ish) and wrote this program to get my head around some of the basics, can someone tell me why this program goes so catastrophically wrong when I run it?

System.out.println("The end of the clock");
System.out.println("The clock took" + realTime + "seconds to finish");
}

That's the code, this is the output, which can tell is wrong:
