weird time for processing date

so i just got my e mail for my processing date, which is on the 12th. but they sent me three different e mails one with the time 9 30, one and 10 30 and the other 11 30... WTF!?! should i just be there at 9 30 or should i call and ask?

If you go on the cedar point job website (the one where you have to login, and it says what kind of job and pay you have) there should be a list of times there showing when you have training classes and when you proccess in. Hope that helps!
