I wrote a blogpost, but in a different blog that I however wanted to link to. It is a blog that is maintained by a bunch of open source digital forensics incident response people some of which are my current team mates.
The blogpost is about Time. More specific on some general ideas and concepts around time. It then goes on to explain how time is relevant in IT and why it is important in digital forensics. It also contains some recommendations that everyone can (and should) apply.
