The TZ environment variable governs what time zone the
message in the install.log contain. The "time zone" config file keyword does not
have any effect on the messages that occur during the install, but
does determine the time zone setting on the target system (the two
can be independently set).
To set the TZ environment variable, it is best to do so in the INSTALLFS file so that it is set as early in the process as possible.
However, the first message will still be in EST since it is produced
before the config file contents of INSTALLFS are read. The procedure for setting this to MST7DT
is:
/opt/ignite/bin/instl_adm -d > /tmp/cur_cfg
echo 'env_vars += "TZ=MST7MDT"' >> /tmp/cur_cfg
/opt/ignite/bin/instl_adm -f /tmp/cur_cfg
