Is birth control still effective if I take it one hour early?

I have been on Lutera for 6 months and have been very diligent about taking it at the same time. I am going on vacation where the time difference is 6 hours (behind) which means I need to take the pill at 3 AM while I am there. If I take it an hour early each day, or every few days, before I leave is the birth control still effective? I don't want to have to wake up at 3AM to take my birth control but will if the effectiveness will be weakened if I change my time.
