So about a month and a half after blogging about this very issue, here we go again. This time I wasn't thinking very deeply about things, so when I tried to install Update 8 and got hit by a File Exists error I contacted Sitecore Support.
Luckily these guys are not without humour, and referred me back to my own blog post for a fix LOL ;-) 1 : 0 to Sitecore Support.
As can be seen, apparently all of these files were created 14/1. Now I have NO idea what I was doing that particular day, but I was wondering.... anyone else having this problem or is it just something really messed up on my development box here?
Gonna get to the bottom of this, one day... :P
