I took Leos code and merged existing functionality of ClipAttr into ClipboardEx.
This is not to bug you Leo and to just rewrite the things you did o). I actually wanted to combine this addin with the existing ClipboardEx addin I already have in use, too much stuff in the script addins folder already. I thought this functionality fits there quite well and I needed something which would copy (only the creation-date) by commandline, directly from A to B without an existing selection.
