How long does Hazel process a "Current Time" rule?

I set up a rule to move all files on the desktop that started with the name "CleanShot" at 11am. At 11am it worked as expected. At 11:01am I added a file that started with "CleanShot" to the desktop, it moved this file as well. The same for 11:02am, 11:03am, and 11:04am. So does Hazel process a "Current Time" rule for 5 minutes?
