Well, my mistake. If OP is still wondering, you only get paid for staying late (at least in my hub). Clocking in before or at your start time doesn't impact your OT pay. Eg, while 2:52 to 7:52 is five hours, overtime doesn't kick in until 8 because we didn't start until 8. Had the start time been 2:45, OT pay would kick in at 7:45.
