javascript getTime() to 10 digits only

Question

I am using the following function to get the Time using javascript:

function timeMil(){
    var date = new Date();
    var timeMil = date.getTime();

    return timeMil;
}

And the value I get is:

1352162391299

While in PHP, I use the time(); function to get Time and the value I get is

1352162391

How do I convert the value of javascript time to remove the last 3 digits and make it 10 digits only.

From 1352162391299
To 1352162391
So that the Javascript time is the same with the PHP time.

I am using a **WAMP** server(_development_) that's why the user and server time are the same. — weyhei, Nov 06 '12 at 00:52

I think you just have to divide it by 1000 milliseconds and you'll get time in seconds

Math.floor(date.getTime()/1000)

but when ticks goes above one more digit, this would fail right? – Kat Lim Ruiz Sep 17 '20 at 04:33

If brevity is ok, then:

function secondsSinceEpoch() {
    return new Date/1000 | 0;
}

Where:

new Date is equivalent to new Date()
| 0 truncates the decimal part of the result and is equivalent to Math.floor(new Date/1000) (see What does |0 do in javascript).

Using newer features, and allowing for a Date to be passed to the function, the code can be reduced to:

let getSecondsSinceEpoch = (x = new Date) => x/1000 | 0;

But I prefer function declarations as I think they're clearer.

So that's cool, but an explanation of what or'ing with zero does would be helpful. – Todd Chaffee Aug 15 '19 at 13:46

Try dividing it by 1000, and use parseInt method.

const t = parseInt(Date.now()/1000);

console.log(t);

but, parseInt only takes a string. `Date.now()/1000` is a number – SeanMC Aug 26 '22 at 15:27

You could divide by 1000 and use Math.floor() on JavaScript.
