how to make javascript to only count the second? -


i have found following script online useful countdown time, want count seconds, e.g count 86400 seconds instead of 10days. if divide 60 @ first one, calculate seconds correctly, , show number, however, static , not moving since second should change every second.how can achieve that? don't understand why divide 1000 @ beginning either because don't know current_date format. appreciate helps.

// set date we're counting down  var target_date = new date("jul 10, 2016").gettime();     // variables time units  var days, hours, minutes, seconds;     // tag element  var countdown = document.getelementbyid("countdown");     // update tag id "countdown" every 1 second  setinterval(function () {         // find amount of "seconds" between , target      var current_date = new date().gettime();      var seconds_left = (target_date - current_date) / 1000;         // format countdown string + set tag value      countdown.innerhtml =  seconds_left + "s";       }, 1000);
<div id="countdown"></div>

try this:

// set date we're counting down  var target_date = new date("aug 15, 2019").gettime();     // variables time units  var days, hours, minutes, seconds;     // tag element  var countdown = document.getelementbyid("countdown");     // update tag id "countdown" every 1 second  setinterval(function () {         // find amount of "seconds" between , target      var current_date = new date().gettime();      var seconds_left = (target_date - current_date) / 1000;         // format countdown string + set tag value      countdown.innerhtml =  seconds_left + "s";       }, 1000);

function gettime() returns milisecond, therfore divided 1000 seconds.
