There are probably several ways of doing this.

One way is to add an extra column and enter the formula


(assuming that your times are in Column B).

Copy this formula down as fat as necessary (hover the cursor over the bottom right of the cell until it turns into a + then hold down the left mouse button and drag down).

Assuming that the column you have just added is D, select all the cells in Column D, Data/Autofilter.

Click the arrow that is added to the top of Colunm D and select 0 from the list. This will hide all the rows that contain times that are not hourly.
