How can one convert a ""Date/Time"" value to a ""Date Only"" value?

Right...but is there a way to ONLY show the time, not the date.  Here's the scenario.  I'm designing a registration system for my office, for visitors that come in to our lobby.  I'm using the Date Created field as the field to determine the time that the visitor arrived, but I don't need to see the date on the table report, just the time.  Make sense?  It's early for a Monday.  :)  Thanks for the help!
