No difference: A woman on combination birth control pills, taking them properly, and is beyond her first pack of pills... has no fertile days. She is not fertile when on birth control pills. That means she has protection against pregnancy every day, regardless of where she is in her pill pack. Switching to a new time a few hours away does not noticeably alter her protection level, meaning there is no difference.

Oral contraceptives: You are right! Keeping to a schedule and taking the pill every day is important to effectiveness of birth control However, 90 minutes difference is not significant and you may switch to the earlier time at your convenience without worrying - today, tomorrow or when you choose.

Yes: If you skip the placebo pills in a pack of birth control pills and go straight to the active pills in the next pack, you shouldn't have a period.

Perfectly safe - Seasonale & Seasoniqe, 2 different birth control pills that promise "Only 4 periods a year" do just this, using formulations of pills currently availible in monthly packs as well. The currrent preference is for a period every 3 months as a minimum, but that's based on women who are NOT suppressing their cycles with pills; there's no data for how long if you are.
