CRM NAV Integration

Hi,

I integrated CRM and NAV using Dynamics Connector. I have mapped the Order Date to Effective from Date and Effective To date to Document Date. While choosing the Effective from and Effective to date in CRM i.e., for example if i give 08/08/2012 (mm/dd/yyyy) it comes as 08/07/2013  in NAV. Suggest us that where we might went wrong.

Thanks
