JavaScript gets the code for the current timestamp

JavaScript gets the current timestamp:
The first method:

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

Results: 1280977330000
The second method:

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

Results: 1280977330748

The above code gets the number of milliseconds that start at midnight on January 1, 1970. The difference between the two is that the first method has an all-zero millisecond, which is just the number of milliseconds that are accurate to seconds

As shown in title, returns the specific time that the Unix timestamp corresponds to:

var time = ' 1278927966 ';
The key is multiplied by 1000, since the time is relative to the beginning of 1970, so 1000 will be transferred to the current time.
var real_time = new Date (time) * 1000;
document.write (Real_time);
