How do you get a timestamp in JavaScript?

Question

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.

Answer 1

new Date().getTime(); // returns the number of MS since the epoch

Answer 2

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

$time()

Answer 3

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

Answer 4

new Date().valueOf()// returns the number of MS since the epoch

Answer 5

I don't have enough points to add a comment to daveb's accepted answer but I think it's worth saying, so I hope you don't mind me putting it here.

One benefit of his way is that the same syntax can be found in other languages. For instance, the following code will give you the exact same timestamp in Java or Scala:

(new java.util.Date()).getTime();

Answer 6

time = Math.round(((new Date()).getTime()-Date.UTC(1970,0,1))/1000);

Answer 7

Is there a solution to disable caching when making the POST/GET

Yes, use jQuery and have a look at the Ajax tutorials.

Answer 8

    var d=new Date();
    var timestamp = new Array(2);
    timestamp[1] = d.getDate();
    timestamp[2] = d.getMonth();
    document.write(timestamp[1]);
    switch (timestamp[2])
      {
      case 0: document.write("Jan");
      break;
      case 1: document.write("Feb");
      break;
      case 2: document.write("Mar");
      break;
      case 3: document.write("Apr");
      break;
      case 4: document.write("May");
      break;
      case 5: document.write("June");
      break;
      case 6: document.write("July");
      break;
      case 7: document.write("Aug");
      break;
      case 8: document.write("Sept");
      break;
      case 9: document.write("Oct");
      break;
      case 10: document.write("Nov");
      break;
      case 11: document.write("Dec");
      break;
      }
