YouMax video upload date - jquery-plugins

Question

I've been using the YouMax plugin which enables you to embed your YouTube channel on your website. However, I am having problems as it displays the uploaded date in months and years. I'd like it to display days, weeks, months and years.
You can view the source code here http://jsfiddle.net/wCKKU/
I believe that its this that needs adjusting to make it calculate in day, weeks, months and years.
function getDateDiff(timestamp) {
if (null == timestamp || timestamp == "" || timestamp == "undefined") return "?";
var splitDate = ((timestamp.toString().split('T'))[0]).split('-');
var d1 = new Date();
var d1Y = d1.getFullYear();
var d2Y = parseInt(splitDate[0], 10);
var d1M = d1.getMonth();
var d2M = parseInt(splitDate[1], 10);
var diffInMonths = (d1M + 12 * d1Y) - (d2M + 12 * d2Y);
if (diffInMonths <= 1) return "1 month";
else if (diffInMonths < 12) return diffInMonths + " months";
var diffInYears = Math.floor(diffInMonths / 12);
if (diffInYears <= 1) return "1 year";
else if (diffInYears < 12) return diffInYears + " years"
}

You could modify the plugin by a small block of code in the middle of the function:
var d2M = parseInt(splitDate[1], 10); // this line is already there
var d1D = d1.getDate();
var d2D = parseInt(splitDate[2],10);
var diffInDays = (d1D + 30 *d1M + 12 * d1Y) - (d2D + 30 *d2M + 12 *d2Y);
if (diffInDays < 2) return "1 day";
else if (diffInDays < 7) return diffInDays+" days";
else if (diffInDays > 7 && diffInDays < 14) return "1 week";
else if (diffInDays > 14 && diffInDays < 30) return Math.floor(diffInDays / 7) + " weeks";
var diffInMonths = (d1M + 12 * d1Y) - (d2M + 12 * d2Y); // this line is already there
Note that this isn't a particularly elegant way to handle the issue, but it matches the coding style the plugin is already using, and at least won't break anything else.
Also, as a side comment, if you're modifying the plugin code you'll want to fix a bug in it at the same time. Getting the current month should look like this:
var d1M = d1.getMonth() + 1;
This is because in Javascript, the getMonth() function returns the month on a zero-based index, and your math won't be reliable unless you switch it to a one-based index.
