Describe the bug

Hours segment repeats twice for the hour "1 AM" on the daylight saving day for the day view and week view.

Minimal reproduction of the problem with instructions

For my case daylight saving day is Nov. 4th, So when I check this day on calendar I see the "1 AM" has repeated twice on this day for both day view and week view. As I checked the Demo at https://mattlewis92.github.io/angular-calendar/#/kitchen-sink act the same, too.

Unfortunately date-fns doesn't have a UTC mode (yet) so the only way to workaround this is by using moment and setting the timezone to UTC. See #477 (comment) for an example.
