in reply to Check if Date interval contains Hour X

I'd suggest taking a look into DateTime::Span.

    I thought you were on to something until I realized the real problem is finding the right date to go with the hour. Using ::Span makes things a lot more complicated since you now need to make 4 DateTime objects for every hour.

      The very first thing that came to my mind after reading the OP was the method DateTime::Span::contains. However, yours is the right approach since that method only works for sets that are fully inside, as the manual says.

      Thanks!

        contains wouldn't work, but intersects would 
        ...| 20 | 21 | 22 | 23 | 00 | 01 | 02 | 03 |...
                  (------------)     log
                            (----]   hour
                            (--)     intersection
