I am starting a new job tomorrow and I have to get up way earlier than I have been. I have been taking my temps at 8am. Is it going to be okay to start taking them at 5:15am or is that going to mess everything up? I don't want my temps to get messed up and drop because of the time. Has anyone had any experience with something like this?
