Surviving Digital Forensics: Understanding OS X Time Stamps

                Welcome to the Surviving Digital Forensics series. This class is focused on helping you get a better understanding of OS X Time Stamps and to become a better Mac examiner. 

                As with previous SDF classes you will learn by doing. The class begins with a brief overview of OS X time - as Apple sees it - then we will get into a number of validation exercises to see how user activity really affects Apple time stamps.  Learning is hands on and we will use applications already installed on your Mac to do so. 

              Expert and novice Mac examiners alike will gain from this class.  Since we are doing it the SDF way we are going to teach you real computer forensic skills that you can apply to all versions of OS X.  Therefore you are not just going to learn about OS X timestamps but learn a method you can use to answer many date and time questions that may come up in the future.
