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.

Answer 1

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

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

Answer 2

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.

Answer 3

Try dividing it by 1000, and use parseInt method.

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

console.log(t);
