Hi i got some in the regard of my question. The steps below to add assembly. 1.In Design view, right-click the design surface outside the border of the report and click Report Properties. 2.Click References. 3.In Add or remove assemblies, click Add and then click the ellipsis button to browse to the assembly.
In you scenario, if you want to add timezone assembly, you can add System.Core. For the detail information about it, please see:

Hope this helps.
