Thanks Divya for the quick response.
I have tried this approach but it didn't work exactly as I wished. Here are the observations:
- It grouped the 2 "abc" groups into one.
- The min and max was presented incorrectly.
For example: if the time range is 12:10:00pm - 1:00:00pm, it will treat
MinTime = 1:00:00 PM
Max Time = 12:10:00PM
