javascript tutorial - timestamp in javaScript - javascript - java script - javascript array

var timeStampInMs = window.performance && window.performance.now && window.performance.timing && window.performance.timing.navigationStart ? window.performance.now() + window.performance.timing.navigationStart : Date.now();

console.log(timeStampInMs, Date.now());

Short & Snazzy:

+ new Date()
if (!Date.now) {
    Date.now = function() { return new Date().getTime(); }
}

To get the timestamp in seconds, we can use:

Math.floor(Date.now() / 1000)

Or alternatively we could use:

Date.now() / 1000 | 0
new Date().getTime()
Math.round(new Date().getTime()/1000)
new Date().valueOf()

We like this, because it is small:

+new Date

We also like this, because it is just as short and is compatible with modern browsers, and over 357 people voted that it's better:

Date.now()

var unix = Math.round(+new Date()/1000);

This will give we the milliseconds since the epoch (not Unix timestamp):

var milliseconds = new Date().getTime();

var time = Date.now || function() {
  return +new Date;
};

time();

var timestamp = Number(new Date()); // current time as number
