get_date function of Generate Attributes Operator

pb42

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.

hello @pb42 so get_date gets a piece of a date for you. For example, if you have that date you showed and you only want the month in a new attribute, you would do

monthOnly                               get_date(att1,DATE_UNIT_MONTH)

so now the attribute would be

att1                                                          monthOnly
Feb 4, 2020 1:52:34 AM EST                 Feb

So, the first element appears to be the attribute name. What does the second element do? Would changing it to DATE_UNIT_YEAR give me the year?

yes. Exactly.
