8480ch02.fm Draft Document for Review January 6, 2020 11:24 pm Syntax format of CLOCKxx IBM supplied default for CLOCKxx Example 2-1 shows the CLOCKxx parameters format. The IBM supplied default PARMLIB member of SYS1.PARMLIB is CLOCK00. If the  STP-related maintenance is installed, CLOCK00 contains the parameters shown in  Example 2-2.

For a detailed description of the statements in the CLOCKxx member see the  MVS Initialization and Tuning Reference , SA23-1380. This specifies whether the operator is to be prompted to set the TOD clock during system  image initialization. The default NOPROMPT specifies that the system image is not to prompt  the operator during TOD initialization unless the TOD clock is not set. OPERATOR PROMPT and SIMETRID are mutually exclusive keywords. If both are specified,  the system image rejects the CLOCKxx member during system image initialization and  issues a message to prompt the operator for specifying a valid CLOCKxx member, or for  using the default values (by pressing the Enter key). Otherwise, the operator must re-IPL the  system image. This specifies the difference between the local time and the UTC. If STPMODE YES and  STPZONE YES are specified and the server is being synchronized using STP messages, the  system image ignores the TIMEZONE parameter.
