html - Javascript setInterval doesn't update timestamp used inside -

i using setinterval in javascript. simple example tried update time displayed.

var tim = new date(); function loadlog(){     document.getelementbyid('timebox').innerhtml=tim.gettime(); } window.setinterval(loadlog, 1000); 

but time not updated. why? how can update variable inside setinterval?

thanks

generate new date each time instead of showing same 1 :

function loadlog(){     var tim = new date();     document.getelementbyid('timebox').innerhtml=tim.gettime(); } window.setinterval(loadlog, 1000);
