Time and Stopwatch Object

This Object implements a Date and Time formatting methods and a stopwatch function.
TimeObj.js listing follows:

//The constructor for TimeObj
function TimeObj(){
  this.Month=1;
  this.Day=1;
  this.Year=0;
  this.Hour=0;
  this.Minute=0;
  this.Second=0;
  this.t=0;
  this.t1=0;
  this.t2=0;
  this.et=0;
}//end TimeObj

//Methods for TimeObj

TimeObj.prototype.updateTime=function(){
   //setup date and time
    this.t = new Date();
    this.Month=this.t.getMonth();
    this.Day=this.t.getDate();
    this.Year=this.t.getFullYear();
    this.Hour =this.t.getHours(); 
    this.Minute=("0"+this.t.getMinutes()).substr(-2);
    this.Second= ("0"+this.t.getSeconds()).substr(-2);
};//end updateTime

// a="M"; b="/"; c="D"; d="/"; e="Y";
TimeObj.prototype.getDate=function(a,b,c,d,e){
var sss="";
  switch (a){
    case 'D': sss+=this.Day;break;
    case 'M': sss+=this.Month;break;
    case 'Y': sss+=this.Year;break;
    default: console.log("getDate Error");
  }//end switch a
  sss+=b;
  switch (c){
    case 'D': sss+=this.Day;break;
    case 'M': sss+=this.Month;break;
    case 'Y': sss+=this.Year;break;
    default: console.log("getDate Error");
  }//end switch c
  sss+=d;
  switch (e){
    case 'D': sss+=this.Day;break;
    case 'M': sss+=this.Month;break;
    case 'Y': sss+=this.Year;break;
    default: console.log("getDate Error");
  }//end switch e
  return sss;
};//end getDate

// a="H"; b="/"; c="M"; d="/"; e="S"
TimeObj.prototype.getTime=function(a,b,c,d,e){
var sss="";
  switch (a){
    case 'H': sss+=this.Hour;break;
    case 'M': sss+=this.Minute;break;
    case 'S': sss+=this.Second;break;
    default: console.log("getTime Error");
  }//end switch a
  sss+=b;
  switch (c){
    case 'H': sss+=this.Hour;break;
    case 'M': sss+=this.Minute;break;
    case 'S': sss+=this.Second;break;
    default: console.log("getTime Error");
  }//end switch c
  sss+=d;
  switch (e){
    case 'H': sss+=this.Hour;break;
    case 'M': sss+=this.Minute;break;
    case 'S': sss+=this.Second;break;
    default: console.log("getTime Error");
  }//end switch e
  return sss;
};//end gettTime

// Stopwatch functions
TimeObj.prototype.SWstart=function(){
  this.updateTime();
  this.t1=this.t;
};//end SWstart

TimeObj.prototype.SWstop=function(){
  this.updateTime();
  this.t2=this.t;
  this.et=this.t2-this.t1;
  return this.et;
};//end SWstop

//end Methods for TimeObj

//Code to test TimeObj
function Testit(){
 var T= new TimeObj();
 T.updateTime();
 T.SWstart();
var aa=[['D','/','M','/','Y'],['M','/','D','/','Y'],['Y','/','M','/','D']];
 console.log(T.getDate.apply(T,aa[0]));
 console.log(T.getDate.apply(T,aa[1]));
 console.log(T.getDate.apply(T,aa[2]));

var bb=[['H','/','M','/','S'],['H',':','M',':','S'],['M','/','S',':','H']];
 console.log(T.getTime.apply(T,bb[0]));
 console.log(T.getTime.apply(T,bb[1]));
 console.log(T.getTime.apply(T,bb[2]));


 console.log(T.SWstop().toFixed(2));
}//end Testit

Testit();

The output of the Testit()function as seen in the left pane of the WebIDE:

>echo(0);
5/4/2016
4/5/2016
2016/4/5
6/59/36
6:59:36
59/36:6
14.58
=undefined
>

One question is about the elapsed time units. The value 14.58 seems a bit long for seconds. Perhaps it is milliseconds.
