Select Administration > Application > Settings.

Select the "Current Application Defaults" tab.

Select the "Display Options" tab.

Review the "Date Format" setting under "Display Options". If this value is not set to "Automatically Detect", reset it. Save the changes, exit Workspace, then log back in.
