Acute care is pretty variable, depending on what you're rotating in. If you're on an admitting service, rounds typically start anywhere from 0700 (more commonly surgery) to 0930 (typically medicine) or anywhere in between. Plan on arriving 1 - 1.5 hours earlier to prep, depending on how many patients you're covering and how efficient you are. Consult services (infectious disease mainly, transplant/cardiology sometimes) round later in the day, typically after the primary service has seen the patient and written their notes for the day. You won't have to get in quite so early for those, but you end up staying in-house later in the day.
Can't speak for industry rotations, but I'd imagine that those are more closely aligned with normal business hours. All bets are off if you're running PK or time-kill studies, though.
