The CLOCKnn Member

In order for the Time Zone feature to work properly, you must check the information in the CLOCKnn member of the SYS1.PARMLIB library, where nn is either the number specified in the IEASYS member in SYS1.PARMLIB, or 00.

You must verify the information in the following statement:

where

• x is either W (West of the Greenwich Meridian, that is, -GMT) or E (East, that is, +GMT)

GMT (Greenwich Mean Time) is also known as UTC (Coordinated Universal Time).

• hh are system time hours
• mm are system time minutes; valid values are either 00 or 30
• ss are system time seconds

For full information on the TIMEZONE statement, see the IBM manual MVS Initialization and Tuning Reference.
