Thank you all very much for your responses and encouragement. I know how to do this in SQL, I was just hoping that SSRS has a faster and easier way perhaps through the reporting code. Is that Excel code? VBA?
What data type is the column that holds this value?
Without an answer to this question, it is impossible to provide a specific answer, but in SSRS, you could do this if the column is a "Date" type:
Add an expression to your "Average Time" :
If the column is actually a string that has been formatted in the data source like HH:MM:SS then you really should take that formatting out of the data source to avoid exactly this sort of problem...however, if that is not an option - you can just convert it back to a date using the TimeValue function, then perform the above calculation in an expression.
There is no need for any "report code" or special handling, just get the data type right and work with it...
