10 hrs of rest lookback is required for you to PILOT a Part 135 flight, not to commute, train, meet, mop, wash, go to get drug tested, etc.   So, you can leave work, go fly home commercially, and THEN duty off!

Then, when you fly back, you duty on leaving your home to travel, and duty off when you get to the hotel/quarters to start your 10 hour rest requirement before you can accept another Part 135 flight.

You can be on duty for 24, 36, 48 hours, you just can't act as a flight crewmember if you can't show 10 hours of rest looking back 24 hours from the completion time of that planned flight.

The duty log reports any and all duty, which includes company travel, meetings, work, beeper duty, janitorial chores, training, etc) because they are all DUTY time!
