The world does not always follow ICAO. I flew for an airline in Asia for a few years and there they logged every flight (all flights were IFR) as instrument time, the entire flight time less 10 minutes (never did figure out why they took off the 10 minutes) and every crewmember logged all that time whether they were downstairs in first class noshing or in the bunk. The FOs got all bothered with me when I would cut them back in the flight log book to show only the flying pilot as instrument time and only for that part of the flight he/she was on the flight deck.
Relevant only because you might be in competition for a job somewhere against one of those bozos.
