$('.comment_date').each(function() {
    $(this).html( $(this).attr('title') );
});

I think this should do it - let me know if that isn't what you're looking for.

It may be worth it to check if the title attribute length is >0. It's best to use .each for cases such as this, otherwise you're setting something to the combined value of multiple elements' values if you don't use .each.

This should do it

$(".comment_date").each(function(i,e) {
  var x = $(e);
  x.html(x.attr("title"));
});

try this:

$(".comment_date").each(function() {
    var cd = $(this);
    cd.html(cd.attr("title"));
});
