Hi doctorfadyriad,
As far as I know, as long as you have the proper papers to back up your claims on your hours, that will be fine. I also used to work overtime and I did not have any problem with it. Check if they schedule you as an intern or as a tech on that day, because in our store, even if I'm an intern pharmacist, in the schedule they put me in as a tech. I made copies of our store schedule, and that served as my proof just in case the board question my hours. Hope this help. =)
