In reality. Start at 1700 hours, depart at 1800 hours, land at 0030 hours. Half way there. Drink coffee until 0230 hours and fly till 0600 hours. Get home at 0700 hours and start again at 1700 hours.
The only thing missing is ILS to the minima after 12 hours duty, hand flying the whole time. You don't know what fatigue is until you do a circling approach single engine, limited panel, inverter failure, at night after 9 hours duty.
Oh and an engine fire.
Nah, I just kidding.
