How to convert outlook date to DateTime?

Question

Hello,

I'm trying to get the sent date from outlook mails. For external mails I got it already running (see: How do I read the Recieved Date from Outlook MSG files -without- the Outlook API?), but for internal mails I get sth. like

"091026132413Z-64"

where

091026 is the date 26.10.2009 (in german file format dd-mm-yyyy) and the rest (or part of it) seems to display the time.

In this case, the mail was sent at 26.10.2009 14:22 (date format dd-mm-yyyy).

So, how do I get from "091026132413Z-64" to "26.10.2009 14:22" ?
