Setting the Year offset value

If you are upgrading a system that observes a non-Gregorian calendar, set the Year offset value before the system is upgraded.

IBM® recommends that you set the Year offset value because your time zone can then be set correctly with this year offset as soon as the upgrade is complete. The IBM i Information Center topic Setting the Year offset value before upgrading the operating system includes the steps for creating a user-defined time zone object and creating the QWCYEAROFS data area in the QSYS library.
