Time Travel needs a way to change scroll intervals. Scrolling 1 minute at a time is so slow it is impractical for looking at the day ahead. Should be able to choose to scroll in 1 mins, 5, 15, 30, 1hr... intervals based upon your preference
Probably not going to happen since Apple has already deprecated the feature since not may use it.
Which information do you want to see?... see the rest off the day.
