You must specify the time zone for your instance. This value is stored in the II_TIMEZONE_NAME environment variable.

Some systems use a default value for II_TIMEZONE_NAME. If you are in a different time zone from the default, you must change the value of II_TIMEZONE_NAME.

Time zone names are organized by world region.

The II_TIMEZONE_NAME parameter tells Ingres what adjustments to make for Daylight Savings Time. If you must make other adjustments for special time changes imposed in your area (such as for energy conservation purposes), you can use the zic time zone compiler provided in the distribution.
