Seconds from Thread

Hello. I am trying to make a timer of sorts that times seconds and minutes. the only problem is the thread I created isn't timing exact seconds like it should. I know that a thread is supposed to sleep for a certain amount ofmiliseconds so why won't it come out even? Making the thread sleep for 16 "miliseconds" is the closest I can get to the real thing but It's still slightly too slow. 17 is too fast. Any ideas?

publicvoid run()

{

while(true)

{

doStuff();

}

}

publicvoid doStuff()

{

try

{

thread.sleep(16);

}

catch(InterruptedException e){}

if(timingcycle == 2)

{

miliseconds++;

if(miliseconds == 60)

{

seconds++;

miliseconds = 0;

if(seconds == 60)

{

minutes++;

seconds = 0;

}

}

}

repaint();

}
