var t = new Date();
t.setSeconds(t.getSeconds() + 10);
For a list of the other Date functions, you should check out MDN
setSeconds will correctly handle wrap-around cases:
var d;
d = new Date('2014-01-01 10:11:55');
alert(d.getMinutes() + ':' + d.getSeconds()); //11:55
d.setSeconds(d.getSeconds() + 10);
alert(d.getMinutes() + ':0' + d.getSeconds()); //12:05 Top answer 1 of 14

How to Add and Subtract Time From a Date in JavaScript | Envato Tuts+
September 19, 2023 - Basically, we’ve just multiplied the number of minutes in an hour (60) by the number of seconds in a minute (60) by the number of milliseconds in a second (1000) to get the number of milliseconds in an hour. As you might already know, you can initialize a Date object by providing the number of milliseconds as the first argument, and this would initialize a date object in reference to it. Thus, we’ve added numberOfMlSeconds and addMlSeconds to get the total number of milliseconds, and we’ve used it to initialize a new date object.
