How to capture the hours from date attribute

Summary:

I am looking to get the current date and then check if it is a time later than 8 pm. But using the getdate(true) on my system I get back the 12 Hour format. I have been able to get the 24 hour format by changing the date to a string with datetostr. What do I use now to identify the hour?

My initial attempt to do this using getdate(true) looked like this. But I never will get any hour larger than 12 in the 12 hour format.
