Grouping date field into hours

I have a date field in qlik sense, [completed_date], that includes all times of the day as number.  I can convert these to day by using Date function, but am trying to figure out if there is a way to group this field by hour. I have used the Hour function, but that does not return the correct information, rather it groups all the days together, then groups by hour.  I tried Date(hour([completed_date])) but, similar results.  I really just want this new dimension to group each day by hour, so I can see, lets say, 9/21/2018 4:00, 9/21/2018 3:00, 9/21/2018 2:00, and so on.  Is there an expression that can be used to achieve this?  Thanks in advance for help.

Use a rounding function like Round(), Floor() or Ceil():

Timestamp(Round(TIMESTAMPFIELD, Maketime(1))) as RoundedToHourTimestamp
