JavaScript gets the current timestamp:
The first method:

Copy Code code as follows:

var timestamp = date.parse (new Date ());

Results: 1280977330000
The second method:
Copy Code code as follows:

var timestamp = (new Date ()). valueof ();

Results: 1280977330748

The above code gets the number of milliseconds from the beginning of Midnight January 1, 1970. The difference is that the first method is full zero in the millisecond bit, which is just the number of milliseconds that is accurate to the second.

As the title shows, returns the exact time that the UNIX timestamp corresponds to:
Copy Code code as follows:

var time = ' 1278927966 ';
The key is multiplied by 1000, because the time is relative to 1970, so multiply by 1000 will go to the current time.
var real_time = new Date (time) * 1000;
document.write (Real_time);

The code simply completes the timestamp conversion.

JavaScript uses the new Date (). GetTime () method

IE8 the above version can be used directly using the Date.now () method

IE8 the following version
if (! Date.now) {
Date.now = function () {return new Date (). GetTime ();
}

JQuery get timestamp $.now ()

var timestamp = $.now ();
