The release upgrade with the Software Update Manager affects also the contents of the SAP database tables that contain time zone information. Therefore, after an upgrade, you must check the time zone settings of your system in all clients used, including client 000. Make sure that they are up to date.

If you have also used time zones that are not part of the current SAP standard, such as the now obsolete time zone “EST_”, you have to add these time zones again manually using transaction STZBC.
