Re: "It's not new behaviour"
Many years ago, doing a stint with a very oldschool solicitor firm which had just gone computery (ah, the old CADO Cat!), they had a signing in book. Each staff member had to enter their name and arrival time.
Part of the office manager's duties involved drawing a thick red line under the most recent arrival's name at 9:00 on the dot so people couldn't fake their arrival time.
