Determine if time is between certain hours

[#1]

Casual jmp 12 user

How do I have jmp determine if a time is between certain hours on any day?

I want to create a column to show (Y/N) if the time when data was taken is between 12:00 AM and 7:00 AM.  So the below data points would be Yes then No.

Data taken at random times and transferred into jmp as shown in the examples below.

    Data (Example)         Between 12 and 7? (Desired result)

11/11/2017 6:44 AM                          Y
11/12/2017 5:28 PM                          N

dt = Current Data Table(); 

dt << New Column("Check",Character,Nominal,Formula(If(Hour(:Data) >= 7 & Hour(:Data) <= 12,"Y","N")));
