Conditional Formatting - Overlapping Time

I would like cells to highlight within a row only if they are non-blank and if other non-blank cells in that row fall within the same time range.

See the attached example for what I'm looking to do. I can setup my sheet one of two ways (as shown) if it makes finding a solution easier.

Thanks!

See attached workbook. I preferred working with the second table as the times were separate and easier to handle.
