The import process of the usage database takes long time to complete on a Microsoft SharePoint Foundation 2010 farm. Therefore, the data in the usage database can be several days older than the current date.
To resolve this issue, apply the following update:
2276341 Description of the Project Server 2010 hotfix package (Wosrv-x-none.msp, Pjsrvwfe-x-none.msp, Osrv-x-none.msp): August 31, 2010
2266423 Description of the SharePoint Foundation 2010 hotfix package (Sts-x-none.msp): August 31, 2010
