Page last updated/saved datestamp on web page?

[vargz]

I'm trying to display a datestamp on each webpage, to show when it was last updated/saved.

I'm using the following code:

function pagedatestamp() {
datUpdated = new Date(document.lastModified) ;
datDate = datUpdated.getDate() ;
datMonth = datUpdated.getMonth() + 1 ;
x = datUpdated.getYear() ;
var datYear = x % 100;
datYear += (datYear < 38) ? 2000 : 1900;
document.write(datDate + "/" + datMonth + "/" + datYear) ;
}

Which is called from a php footer include, but it seems to show the current date (which I think is being taken from the PC clock) instead of showing the date when the page was last saved/updated.

How do I go about achieving this, in javascript or even with php?

Here is a function that will help you out, maybe you can learn from it.

http://www.quirksmode.org/js/lastmod.html

function lastMod() {
	var x = new Date (document.lastModified);
	Modif = new Date(x.toGMTString());
	Year = takeYear(Modif);
	Month = Modif.getMonth();
	Day = Modif.getDate();
	Mod = (Date.UTC(Year,Month,Day,0,0,0))/86400000;
	x = new Date();
	today = new Date(x.toGMTString());
	Year2 = takeYear(today);
	Month2 = today.getMonth();
	Day2 = today.getDate();
	now = (Date.UTC(Year2,Month2,Day2,0,0,0))/86400000;
	daysago = now - Mod;
	if (daysago < 0) return '';
	unit = 'days';
	if (daysago > 730) 	{
		daysago = Math.floor(daysago/365);
		unit = 'years';
	}
	else if (daysago > 60) {
		daysago = Math.floor(daysago/30);
		unit = 'months';
	}
	else if (daysago > 14) {
		daysago = Math.floor(daysago/7);
		unit = 'weeks'
	}
	var towrite = 'Page last changed ';
	if (daysago == 0) towrite += 'today';
	else if (daysago == 1) towrite += 'yesterday';
	else towrite += daysago + ' ' + unit + ' ago';
	return towrite;
}
 
 
function takeYear(theDate) {
	x = theDate.getYear();
	var y = x % 100;
	y += (y < 38) ? 2000 : 1900;
	return y;
}

..and calling it.

document.write(lastMod())

Thanks but I already tried this - does the same thing but just puts it in terms of how many days ago the page was last updated.

Anyone else know a way to achieve this?
