Returning the wrong number of days.

For some reason the number of days the code is returning is 2 should be 1.  Here is my code below

Date.prototype.todaydiff = function(tstamp){
 this.timestamp=tstamp;
var one_day=1000*60*60*24;
    
    var today = new Date();
var dateA = new Date(new Date().getUnixTime());
/*Calculation for timezone offset */
var dateB = new Date(this.timestamp*1000 + today.getTimezoneOffset() * 60000);
    
     // Convert both dates to milliseconds
  var date1_ms = dateA.getTime();
  var date2_ms = dateB.getTime();

  // Calculate the difference in milliseconds
  var difference_ms = date1_ms-date2_ms;
    

 return Math.round(difference_ms/one_day); 
};

var myDate = new Date()
console.log(myDate.todaydiff(1436227200));

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

It seems close. You don't need to add the time zone offset. Also what is "getUnixTime()"? That's not a standard method.

Try this:
Date.prototype.todaydiff = function(tstamp){
  this.timestamp=tstamp;
  var one_day=1000*60*60*24;

  var dateA = new Date();
  var dateB = new Date(this.timestamp*1000);

  // Convert both dates to milliseconds
  var date1_ms = dateA.getTime();
  var date2_ms = dateB.getTime();

  // Calculate the difference in milliseconds
  var difference_ms = date1_ms-date2_ms;

  return Math.round(difference_ms/one_day); 
};

var myDate = new Date()
//console.log(myDate.todaydiff(1436227200));
var myDate2 = new Date(myDate.getFullYear(),myDate.getMonth(),myDate.getDate()-1)
console.log(myDate.todaydiff(myDate2.getTime()/1000));
