The excellent Pogo69 blog, which is an excellent resource for CRM developers has a blog post with a nice piece of Javascript to find the difference between two dates using Javascript.
He mentions that he is starting to build a Javascript library, which thanks to CRM 2011 we can now do because you can use the same Javascript file in many forms.
I am surprised that Microsoft haven’t already created some general Javascript libraries for everyone to use, surely their developers would have already done something like that or at least created enough Javascript to make one.
if (typeof DateLib == 'undefined') {
DateLib = {};
}
DateLib.Diff = function (from, to) {
return to - from;
}
DateLib.DiffMinutes = function (from, to) {
return DateLib.Diff(from, to) / (1000 * 60);
}
DateLib.DiffParts = function (from, to) {
var diff = DateLib.DiffMinutes(from, to);
var parts = new Object();
parts.Days = Math.floor(diff / (60 * 24));
diff -= (parts.Days * 60 * 24);
parts.Hours = Math.floor(diff / 60);
diff -= (parts.Hours * 60);
parts.Minutes = Math.floor(diff);
parts.Display =
(parts.Days > 0 ? parts.Days + " days, " : "") +
(parts.Hours > 0 ? parts.Hours + " hrs, " : "") +
(parts.Minutes + " mins");
return parts;
}

You can edit the existing notes functionality so you will need to create new functionality. I would probably create a new entity
