javascript time in milliseconds code example

Example 1: javascript get time

// these are the most useful ones IMO
var time = new Date();
time.getDate(); // returns value 1-31 for day of the month
time.getDay(); //returns value 0-6 for day of the week
time.getFullYear(); //returns a 4 digit value for the current year
time.getHours(); //returns value 0-23 for the current hour
time.getMinutes(); //returns value 0-59 for the current minute of the hour
time.getSeconds(); //returns value 0-59 for current second of the minute
time.getMilliseconds(); //returns value 0-999 for current ms of the second
time.getTime(); //returns date as ms since Jan 1, 1970
time.toDateString(); //returns a string (e.g. "Fri May 9 2020")
time.toLocaleString(); //returns date and time (e.g. "9/12/2015, 6:08:25 PM")
time.toLocaleTimeString(); //returns time (e.g. "6:08:25 PM")
time.toLocaleDateString(); //returns date (e.g. "9/12/2015")

Example 2: what 1hr in milliseconds in javascript

/*

15 minutes = 900000 milliseconds
30 seconds = 30000 milliseconds	
1 minute = 60000 milliseconds
5 minutes = 300000 milliseconds
30 minutes = 1800000 milliseconds
45 minutes = 2700000 milliseconds
1 hour = 3600000 milliseconds

*/

Example 3: js get date in ms

Date.now() // 1602680486141

Example 4: javascript get Time

var d=new Date();
d.getTime();//I'm in milliseconds, divide by 1000 for seconds

Example 5: convert milliseconds to time javascript

function msToTime(s) {

  // Pad to 2 or 3 digits, default is 2
  function pad(n, z) {
    z = z || 2;
    return ('00' + n).slice(-z);
  }

  var ms = s % 1000;
  s = (s - ms) / 1000;
  var secs = s % 60;
  s = (s - secs) / 60;
  var mins = s % 60;
  var hrs = (s - mins) / 60;

  return pad(hrs) + ':' + pad(mins) + ':' + pad(secs) + '.' + pad(ms, 3);
}

console.log(msToTime(55018))
