【求助】此代码如何实现每秒执行一次

<script type="text/javascript">
	function timeElapse(date) {
		var current = Date();
		var seconds = (Date.parse(current) - Date.parse(date)) / 1000;
		var days = Math.floor(seconds / (3600 * 24));
		seconds = seconds % (3600 * 24);
		var hours = Math.floor(seconds / 3600);
		if(hours < 10) {
			hours = "0" + hours;
		}
		seconds = seconds % 3600;
		var minutes = Math.floor(seconds / 60);
		if(minutes < 10) {
			minutes = "0" + minutes;
		}
		seconds = seconds % 60;
		if(seconds < 10) {
			seconds = "0" + seconds;
		}
		var result = "" + days + " days " + hours + " hours " + minutes + " minutes " + seconds + " seconds";
		$("#elapseClock").html(result); 
	}
	timeElapse(new Date("2018/09/10"))	
</script>
