Here in Austria, most of winter (or maybe year?...) there are actually no parts of a day. No dawn, morning, or afternoon and time runs only in clocks. This is a random day example, taken yesterday. I could make the same for the most of a month's days.
First foto, taken about 11.30'

2nd, 12.30'

13.30'

14.30'

15.30'

16.30'

17.30' (after a perfect day, the night came to give people rest)

(Unfortunately I lost yesterday's 10.30 foto. No problem, here is today's 10.30 foto. : ) )
