DA time is something that originated in the testlab. It used to be used by hardworking people in reference to people who weren't doing their job. It has been revised a bit, and is now used to describe what we've been doing collectively for the last 3 days. In case you were wondering, DA stands for Dick Around. We have another day of Dick Around time.
This would be more wonderful, if I could remember all of the things I used to do on the interwebs to take up all of my time.
