Metadata Jacket Modification Issues

[Atherton25]

Hello gentlemen (and women). I have a problem that hopefully someone can answer without going to the almighty authority.

A long time ago I modified my jacket. It wasn't perfect, but it was okay. I really prefer (at minimum) showing size with words and/or pages. I upgraded my computer and decided I needed to get it right this time - something I like the look of more.

So, I've been playing with the hacket HTML to get it to show more information such as Words (word count), Score (my personal star rating), Date (when it was added to my library) etc. Most of it seems to work fine, but there are a couple of information columns I'd like to add that don't seem to want to.

First, I'd like to add the 'Date' Column - when it was added to my computer. given that {rating_label} and {tags_label} both work, I assumed that the other built in columns would be similar.
For the labels, I tried several that don't seem to work. These include, but are not limited to (I didn't go through all of them):
{publisher_label}, {timestamp_label}, {last_modified_label}
The latter to don't matter as much, as barring some issues, they're ALWAYS there, so I can just overwrite them as 'Added Date' and 'Last Modified' but I'm just noting they don't work.

In other cases, specifically publisher, I would like to have a label there, and I could manually enter it, just putting the actual name (IE Publisher: instead of {publisher_label}) but the problem is that that particular column isn't always filled, and doesn't allow the element to disappear if the information doesn't exist.

The other larger problem is the actual information. While {pubdate} works fine,{timestamp} and {last_modified} do not. I can't seem to find what other value they may be under, or if I need to format them somehow (I'd love that, as I prefer my date format backwards from what most people do).

I have read the forums looking for answers, as well as the 'Overriding icons, templates, et cetera' area of the help manual. It's possible I've missed something or am not using the correct phrasing in search. Can anyone help me out?

I've attached a sample template just so someone can look at it if they'd like, as well as a sample of what my jacket problem looks like with comments.

So I guess it wasn't an option. Thank you for making modifications.
