DateTimeOffSet Issue

Hi,

I have a tsql query that returns a datetimeoffset value. This is used as a parameter. I cast this to a datetime value but SSRS still has a problem with it - when I click 'View Report', this parameter gets reset.

SELECT cast(r.[datetime] as DateTime) RunDate
FROM Records r

Above is my query to populate the parameter. I know SSRS has issues with DateTimeOffSet but not sure how to get around it.

Any ideas?

Thanks!
