Setting the Time zone (QTIMZON) system value
You can set the QTIMZON system value before upgrading IBM i software, either during an initial program load (IPL) or after the installation using IBM Navigator for i.
The method that you use depends on whether you are upgrading
from a previous release, or installing the operating system. Otherwise,
you can always work with the time zone using IBM Navigator
for i.
Note: If a change
to a different time zone description results in a different offset,
the change will cause the local system time, system value QTIME, to
change. In addition, the system value QUTCOFFSET will change to match
this new offset.
