How To Make A Simple Stopwatch In Javascript

this is the look of the stopwatch

the script add it below head

function clearALL() {
clearTimeout(clocktimer);
h=1;m=1;tm=1;s=0;ts=0;ms=0;
init=0;show=true;
readout='00:00:00.00';
document.clockform.clock.value=readout;
var CF = document.clockform;
for (ij=0;ij<=9;ij++) { CF[mPLUS[ij]].value = ''; }
ii = 0;}

function addMEM() {
if (init>0) {var CF = document.clockform;
CF[mPLUS[ii]].value = readout;
if (ii==9) { ii = 0; } else { ii++; }}}

function startTIME() { 
var cdateObj = new Date();
var t = (cdateObj.getTime() - dateObj.getTime())-(s*1000);

if (t>999) { s++; }

if (s>=(m*base)) {ts=0;
m++;} else {ts=parseInt((ms/100)+s);
if(ts>=base) { ts=ts-((m-1)*base); }}

if (m>(h*base)) {tm=1;
h++;} else {tm=parseInt((ms/100)+m);
if(tm>=base) { tm=tm-((h-1)*base); }}

ms = Math.round(t/10);
if (ms>99) {ms=0;}
if (ms==0) {ms='00';}
if (ms>0&&ms<=9) { ms = '0'+ms; }

if (ts>0) { ds = ts; if (ts<10) { ds = '0'+ts; }} else { ds = '00'; }
dm=tm-1;
if (dm>0) { if (dm<10) { dm = '0'+dm; }} else { dm = '00'; }
dh=h-1;
if (dh>0) { if (dh<10) { dh = '0'+dh; }} else { dh = '00'; }

readout = dh + ':' + dm + ':' + ds + '.' + ms;
if (show==true) { document.clockform.clock.value = readout; }

clocktimer = setTimeout("startTIME()",1);}

function findTIME() {
if (init==0) {dateObj = new Date();
startTIME();
init=1;} else {if(show==true) {show=false;} else {show=true;}}}
</script>

this is the form code
