回答1:

You can use the TimeStamp class gether with the Sum function, follow an example:

=TimeSpan.FromMinutes(Sum(Fields!Dirigindo.Value))

回答2:

You need to either calculate it in the Dataset. Perhaps casting it to a proper date time format (you can give it a dummy date component such as 1900-01-01 and then perform the calculation use Datediff):

or use an SSRS expression using the TimeSpan object:
