AMC did not compensate pilots for time worked before their scheduled shift until they were sued in California. Time spent preflighting (which was required by AMC) showed on a pilot's timesheet as 15 minutes preflight "UNPAID". 

In May 2020, AMC began paying California pilots for 15 minutes of preflight and no more than that, regardless of when the pilot shows up. So if you clock in 25 minutes early, you only get paid for 15 minutes. It shows up on your timesheet as "PREFLIGHT, 15 minutes"

Your pay ends when your scheduled shift ends even if you stay a bit longer. Your timesheet shows "Shift, 12 hours". If you clock out later, a manager will change it to reflect 12 hours unless you were on a flight or had a meeting, etc.
