CLOCKS

The CLOCKS macro is used to specify the current status of the clocks used in the online system. The parameters are used to set up the time fields in CTKA, CTKB and CTKX.

The CLOCKS macro is required.

Format




GDIF=shhmm
Specifies difference between Local Standard Time and Greenwich Mean Time (GMT-LST) in signed (+,-) EBCDIC 2400 hour representation. The difference must be between -1200 and +1200.

LST=hhmm
Specifies local time in EBCDIC 2400 hour representation to be used before the system is cycled above 1052 state for the first time.

DATE=mm/dd/yy
Specifies the date the system clocks will use before the system is cycled above 1052 state for the first time, where mm=month, dd=day, and yy=year. If the year (yy) is between 73 and 99 (that is, between the years 1973 and 1999), assume the date is 19xx; otherwise, assume the year is 2000 or above (2000-2072).
Note:
Before the system is cycled above 1052 state for the first time, the perpetual minutes clock and last midnight values in CTKB are initialized using the values specified by the DATE= and LST= parameters. Time and date displays will reflect these values. When the system is cycled above 1052 state, the clock values in CTKB are replaced with values calculated using a base date of 01/03/66 and the current time from the hardware TOD clock. Time and date displays will then reflect the current time and date.

DELTIM=hhmm
Specifies the subsystem time difference from the system clock. This parameter is specified as hh (hours) and mm (minutes). A maximum of up to 24 hours may be specified. This parameter is only valid in a TPF system with multiple database function (MDBF) support and should only be specified for nonbasic subsystem type generations.

SDIF
Specifies the difference between Greenwich Mean Time (GMT) and the system clock (GMT-system clock) in signed (+,-) EBCDIC 2400 hour representation. The difference must be between -1200 and +1200. The default value is 0.

Examples

The following specifies a plus 5-hour difference between the local time of the installation and Greenwich Mean Time. The local time is 3:00 P.M. and the date is May 21, 1996. Because SDIF is not specified the system clock is assumed to be set to GMT. SDIF is set to 0 by default.
