Thanks for the ddl and data. What I don't understand is the desired output. Since WKBW has a bit fewer rows let's look at that one.
OUTPUT
WKBW 7/5/13 12:00 PM 7/5/13 2:00 PM
WKBW 7/9/13 11:30 AM 7/9/13 12:30 PM
WKBW 7/12/13 12:30 PM 7/17/13 1:00 PM
WKBW 7/19/13 12:30 PM 7/19/13 2:00 PM
Not sure why your skip the first row 11am - 11:30am and start with the row that begins at noon. Do you only want groups where there are least 2 consecutive times or am I missing something?
Also, why do you have one row that starts on 7/12 but end on 7/17? There is nothing in the data to suggest that. What about the 18th?
