javascript - calculate time difference

Question

I have a jQuery clock that gives the time from 00:00 to 23:00.

Now I want to calculate the time difference between two times. Suppose the "in" time is 11:00, and the "out" time is 16:00.

How do I calculate the time difference in javascript?

Answer 1

You can use Date and setHours like that:

var first = new Date();
first.setHours(0, 11, 0, 0);

var second = new Date();
second.setHours(0, 16, 0, 0);

alert("Diff in seconds: " + (second - first));
