Yes. They are highly unlikely to accommodate this request. You MIGHT get them issue you a refund because of the time change, but as Flyerco said, that does require 90 minutes.

The only reason I could see them changing the date is that you could say that the new time is too late for you to arrive, but the earlier flights don't work, and could you please put me on the first flight out the following morning. That MIGHT work, especially because the new arrival date is already the next day.
