How do you get a timestamp in JavaScript?
How can I get a timestamp in JavaScript?
Something similar to Unix's timestamp, that is, a single number that represents the current time and date. Either as a number or a string.
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());I like this, because it is small:
+new Date
I also like this, because it is just as short and is compatible with modern browsers, and over 500 people voted that it is better:
Date.now()
JavaScript works with the number of milliseconds since the epoch whereas most other languages work with the seconds. You could work with milliseconds but as soon as you pass a value to say PHP, the PHP native functions will probably fail. So to be sure I always use the seconds, not milliseconds.
This will give you a Unix timestamp (in seconds):
var unix = Math.round(+new Date()/1000);
This will give you the milliseconds since the epoch (not Unix timestamp):
var milliseconds = new Date().getTime();
