- Offset from UTC
- Standard time names
- DST names
- DST start
- DST end
- Year offsetNote: The Year offset information is not shown on systems running IBM i V5R4, or earlier. It is also not shown if the value is zero.
You can access the Time zone system value from two locations in IBM Navigator for i. To view the current time zone, select . Right-click on Date and Time and click Properties, then switch to Time tab. To work with the time zones, select . Right-click on Time Zones and click Open.
