get_date function of Generate Attributes Operator

I am trying to understand how the generate an Hour of the Day attribute from a Date attribute. The date attribute looks like this:  Feb 4, 2020 1:52:34 AM EST. 

I have been trying to determine what are the elements of the date_get function, but cannot figure that out. If I had an example of what goes into the function that may help. The information button provides a generic example, but that does  not make sense to me.
