When trying to do a GSX lookup etc. and if you receive this error window that says "Unit Received Data cannon be a future date error"
This means that the workstation you are using does not have the correct Local Time Zone Offset setting. This is needed by Apple in order for GSX to receive the correct time.
*Any workstation that needs to communicate with GSX needs to have the proper Local Time Zone Offset settings.
* You will also need to update this setting if your region take part in Daylight Savings time.
To update this setting Go to Admin> Workstation> make sure you have the Preferences button selected then go to the Local Time Zone Offset param and choose the appropriate one for your location. If you are in DST (Daylight Savings Time) you need to increase the number. For example, if you are -5 then you need to make it -4. - If you are in 3 then make it 4 etc. - but in the fall you need to put it back to the original # listed in the "i" pull down menu that shows you your options.
