Telling if date format includes time

Hello lbendlin, thank you for your reply 🙂

I think your suggestion is good, but I am worried about performance of it. Because, to determine if something is a date format, we would theoretically need to evaluate every single value, would we not? If we check the first value and find it's a date, we can't exclude the possibility that the value after that may be datetime (and so on and so on). 

Either way, I've thought about it and believe that it's best to consider all date measures passed to be datetime. I will just include an option for users to specify if they want it to be date after the fact (while still using their formatting no matter what it is). I think this gives the end-user more flexibility.

Thanks for your help!
