Regional settings and date formatting
For those Reporting Services reports that are made available to all clients, Siriusware Inc. makes every effort to ensure that date formatting reflects the client’s regional settings.
Example:
Clients in the United States may expect to see July 4th, 2013 represented as 7/4/2013, while clients in New Zealand or Australia would expect it to appear as 4/07/2013. Reports are designed to use the default settings on the system, but these settings can be adjusted in multiple places (both client and server-side) and each could affect how reports appear.
