I have two datetime fields and I need to show the difference between them. I've used this expression to calculate it:
=DateDiff("n", Fields!hra_atncion.Value, Fields!fcha_incio.Value)
The result column should be on HH:mm, but the result is a Long expression type. Something like 428011156
Any answer will be apreciated!
UPDATE 21/11/2013
How I obtain the time difference in minutes between 12-11-2013 20:00 and 14-11-2013 08:00 ?
