Convert normal date to unix timestamp

How can I convert normal date 2012.08.10 to unix timestamp in javascript?

Fiddle: http://jsfiddle.net/J2pWj/




I've seen many posts here that convert it in PHP, Ruby, etc... But I need to do this inside JS.

Answers:

Answer
new Date('2012.08.10').getTime() / 1000

Check the JavaScript Date documentation.

Answer
parseInt((new Date('2012.08.10').getTime() / 1000).toFixed(0))

It's important to add the toFixed(0) to remove any decimals when dividing by 1000 to convert from milliseconds to seconds.

The .getTime() function returns the timestamp in milliseconds, but true unix timestamps are always in seconds.

Answer

You should check out the moment.js api, it is very easy to use and has lots of built in features.

I think for your problem, you could use something like this:

var unixTimestamp = moment('2012.08.10', 'YYYY.MM.DD').unix();
Answer

You could simply use the unary + operator

(+new Date('2012.08.10')/1000).toFixed(0);

http://xkr.us/articles/javascript/unary-add/ - look under Dates.

Answer

You can do it using Date.parse() Method.

Date.parse($("#yourCustomDate).val())

Date.parse("03.03.2016") output-> 1456959600000

Date.parse("2015-12-12") output-> 1449878400000

Answer
var datestr = '2012.08.10';
var timestamp = (new Date(datestr.split(".").join("-")).getTime())/1000;
Answer

After comparing timestamp with the one from PHP, none of the above seems correct for my timezone. The code below gave me same result as PHP which is most important for the project I am doing.

function getTimeStamp(input) {
    var parts = input.trim().split(' ');
    var date = parts[0].split('-');
	var time = (parts[1] ? parts[1] : '00:00:00').split(':');

	// NOTE:: Month: 0 = January - 11 = December.
	var d = new Date(date[0],date[1]-1,date[2],time[0],time[1],time[2]);
	return d.getTime() / 1000;
}

// USAGE::
var start = getTimeStamp('2017-08-10');
var end = getTimeStamp('2017-08-10 23:59:59');

console.log(start + ' - ' + end);

I am using this on NodeJS, and we have timezone 'Australia/Sydney'. So, I had to add this on .env file:

TZ = 'Australia/Sydney'

Above is equivalent to:

process.env.TZ = 'Australia/Sydney'
Answer

var d = '2016-01-01T00:00:00.000Z';
console.log(new Date(d).valueOf()); // returns the number of milliseconds since the epoch

Answer
var date = new Date('2012.08.10');
var unixTimeStamp = Math.floor(date.getTime() / 1000);

In this case it's important to return only a whole number (so a simple division won't do), and also to only return actually elapsed seconds (that's why this code uses Math.floor() and not Math.round()).

Answer

You can use Date.parse(), but the input formats that it accepts are implementation-dependent. However, if you can convert the date to ISO format (YYYY-MM-DD), most implementations should understand it.

See Why does Date.parse give incorrect results?.

Answer

convert timestamp to unix timestamp.

const date = 1513787412; const unixDate = new Date(date * 1000);// Dec 20 2020 (object)

to get the timeStamp after conversion const TimeStamp = new Date(date*1000).getTime(); //1513787412000
