If your employer requires you to come to a meeting that was scheduled in advance and on a day you do not normally work - and the meeting ends early - you should be entitled to reporting time pay if it lasts for less than half of the projected time. So if what was supposed to be a two-hour meeting lasts 59 minutes, you should get two hours of reporting time. Though if what is supposed to be a two hour meeting lasts 61 minutes, then you'd get only 61 minutes of your regular rate of pay.
