He assumed I was not working or doing work for a different manager (they implemented matrix management and he was at HQ 70 km away from the town I worked at). I made a judgement call as that migration was a $20 mln project. That corporation had time budgeting. I was supposed to account in a production tracking system every task I did in 15 minute granularity. I have a ton of crazy stories like that out of that place.

In essence, the guy was a micromanager with trust issues. They later replaced him, with someone that was actually worse.
