timestamp in JavaScript:<\/strong>
\nThe Date.now() method returns the number of milliseconds elapsed since 1 January 1970 00:00:00 UTC.<\/p>\n

Syntax<\/strong><\/p>\n

jQuery Code<\/span> <\/div> 
var timeInMs = Date.now();\t\tvar timeStamp = Math.floor(Date.now() \/ 1000);<\/code><\/pre> <\/div>\n[ad type=”banner”]\n
Get a UNIX timestamp with Javascript<\/p>\n
 
 jQuery Code<\/span> <\/div> 
var ts = Math.round((new Date()).getTime() \/ 1000);<\/code><\/pre> <\/div>\n
Return value<\/strong><\/p>\n
A Number representing the milliseconds elapsed since the UNIX epoch.<\/p>\n
Description<\/strong><\/p>\n
Because now() is a static method of Date, we always use it as Date.now().<\/p>\n
Usage<\/strong><\/p>\n
Date.getUnixTime() returns the Unix epoch time.
\nDate.now() polyfill for older browsers.
\nDate.time() is a a C-style helper function that returns the current Unix time.<\/p>\n
Example1:<\/strong><\/p>\n
Date.getUnixTime() returns the Unix epoch time.<\/p>\n
We frequently need to calculate with unix timestamp. There are several ways to grab the timestamp. For current unix timestamp easiest and fastest way is<\/p>\n
 
 jQuery Code<\/span> <\/div> 
const dateTime = Date.now();const timestamp = Math.floor(dateTime \/ 1000);<\/code><\/pre> <\/div>\n
or<\/p>\n
 
 jQuery Code<\/span> <\/div> 
const dateTime = new Date().getTime();const timestamp = Math.floor(dateTime \/ 1000);<\/code><\/pre> <\/div>\n
To get unix timestamp of a specific date pass YYYY-MM-DD or YYYY-MM-DDT00:00:00Z as parameter of Date constructor.<\/p>\n
 
 jQuery Code<\/span> <\/div> 
const dateTime = new Date('2012-06-08').getTime();const timestamp = Math.floor(dateTime \/ 1000);<\/code><\/pre> <\/div>\n
we can just add a + sign also when declaring a Date object like below<\/p>\n
 
 jQuery Code<\/span> <\/div> 
const dateTime = +new Date();const timestamp = Math.floor(dateTime \/ 1000);<\/code><\/pre> <\/div>\n
[ad type=”banner”]\n
or for specific date<\/p>\n
 
 jQuery Code<\/span> <\/div> 
const dateTime = +new Date('2012-06-08');const timestamp = Math.floor(dateTime \/ 1000);<\/code><\/pre> <\/div>\n
Example2:<\/strong><\/p>\n
Date.now() polyfill for older browsers.<\/p>\n
This method was standardized in ECMA-262 5th edition.
\nEngines which have not been updated to support this method can work around the absence of this method using the following shim:<\/p>\n
 
 jQuery Code<\/span> <\/div> 
if (!Date.now) {  Date.now = function now() {    return new Date().getTime();  };}<\/code><\/pre> <\/div>\n
Solution<\/strong><\/p>\n
To copy & paste the following code at the beginning of your JavaScript:<\/p>\n
 
 jQuery Code<\/span> <\/div> 
Date.prototype.getUnixTime = function() { return this.getTime()\/1000|0 };if(!Date.now) Date.now = function() { return new Date(); }Date.time = function() { return Date.now().getUnixTime(); }<\/code><\/pre> <\/div>\n
