With the release of v7.4.2, we introduced the ability to change your portal's "Home Time Zone" from the default "CST" to whatever you choose.
To perform this action, visit Module Tools -> Portal Framework -> Set Home Time Zone. Choose your zone from the drop down, then click OK.
This will impact Documents, Pages - anything in framework with a time stamp will now use this time, instead of the default time. It also impacts Announcement and Help Desks.
Important Note: Help Desks is currently the only add-on application chosen to receive this update. If you are a RackSpace user and feel this update should be applied to another add-on application, please open a Product Change Request ticket and let us know!
*It does not work yet in one known framework area: Page Hit By Hour Report (Usage Traffic) - we missed that one! We will add it as soon as we can.
