## Syntax format of CLOCKxx 

Example 2-1 shows the CLOCKxx parameters format. 

OPERATOR {PROMPT } | {NOPROMPT} TIMEZONE d.hh.mm.ss ETRMODE {YES} | {NO } ETRDELTA nn ETRZONE {YES} | {NO } SIMETRID nn STPMODE {YES} | {NO } TIMEDELTA nn STPZONE {YES} | {NO } ACCURACY mmmmm ACCMONINTV {mmss | mss} 

## IBM supplied default for CLOCKxx 

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. 

OPERATOR NOPROMPT TIMEZONE W.00.00.00 STPMODE YES STPZONE YES TIMEDELTA 10 ACCURACY 0 

## Statements and parameters for CLOCKxx 

This section identifies the CLOCKxx statements and provides a short description of each statement. For a detailed description of the statements in the CLOCKxx member see the MVS Initialization and Tuning Reference , SA23-1380. 

## OPERATOR {PROMPT | NOPROMPT} 

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. 

## TIMEZONE d.hh.mm.ss 

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.
