Usually I don't time travel days at a time, I mainly just set the clock back and forth because I work from 8am-4pm, and sometimes I play before work and want everything to be open so I can go ahead and sell fruits, fish, and fossils and browse the shops before I have to get off! And once I'm off work, I usually play until it gets dark, or go ahead and set my clock forward so I can go to the island for some bugs and fish.
