My date is: 2020-04-30 16:51:42

My expected output is: 2020-04-30 16:51:52

Answer 1

You can use Date.setSeconds() method to set the seconds.

Look at this link: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/setSeconds

Answer 2

You can use this code

var d = new Date("2020-04-30 16:51:42");
d.setSeconds(d.getSeconds()+10);
console.log(d);

Better idea is convert to millis long number and add (10 * 1000)

var d = new Date("2020-04-30 16:51:42");
var mil = d.getTime();
mil = mil + (10 * 1000)
console.log(new Date(mil));

1000 millisecond = 1 second

For Safari browser this format will work

var d = new Date("2020/04/30 16:51:42");
