custom time period analysis function

I would like to allow users change time period in the following
Tomorrow 05:00 – 09:00
Morning 09:00 – 13:00
Afternoon 13:00 – 17:00
Evening 17:00 – 21:00
Midnight 21:00 – 01:00
Night 01:00 – 05:00

If you like the change, please vote it or comment.
If more users like it, I will develop it soon.
