After you install the hotfix package that is described in Microsoft Knowledge Base article 952288, the Site Collection Usage Summary page is broken

After you install the hotfix package that is described in Microsoft Knowledge Base article 952288, the Site Collection Usage Summary page does not load correctly. On the Site Collection Usage Summary page, the number of users that is listed in the Number of Users entry is much lower than the actual number of users who have been added to the site collection.

Note This issue occurs one day after you restart Internet Information Services (IIS) by using the IISReset command prompt utility.

The issue occurs because access statistics are collected based on the Greenwich Mean Time (GMT) time zone. Therefore, non-GMT time zone data is split between two days.

To resolve this issue, apply the following hotfix package:

Limitation

You cannot import current usage data after you install the hotfix package. Therefore, you must import current usage data before you install the hotfix package. Also, the usage data from the start date (day x) can usually can be imported only one day later (day x+1). To work around this limitation, rename the log folder according to the new naming rules.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
