Hello again, tnx for the answer!

I've now another problem, since i have to recalcute all the history of my service desk to show in a report, i've to change your code to accept the start and the end date.

I've change your code to accept two parameters, start date and End Date, but when i change the getdate() to enddate parameter, when i execute the function "select dbo.ufninc_CalcTimeSinceCreated (getdate(),getdate()+1)" it return 9 hours instead of the 8 hours.

Do you know why?
