iizck Command—Display Time Zone Table Files

Permission required: Access to the directory where the utility is located.

The iizck utility displays the time zone table files. You can check the time zone table currently in effect or a newly created one.

The display shows the Greenwich Mean Time (GMT) offset for the time zone. For those timelines adjusted for Daylight Savings Time (DST), it gives each date that the GMT offset changed.

If no parameters are specified, the iizck utility displays the II_TIMEZONE_NAME table.

The iizck command has the following format:

iizck [-name=timezone_name] [-fpathname/filename]

• -name=timezone_name

  Specifies the name of the time zone table currently in effect.

• -fpathname/filename

  Specifies the path and name of a new time zone table.
