Date formats used in IBM Z Workload Scheduler

Different components of IBM Z Workload Scheduler use different formats to represent dates, as described hereafter.

Table 1. Date formats used in IBM Z Workload Scheduler
IBM Z Workload Scheduler component	Date format	Length	Date type
Controller	YYMMDD	6	Internal date
Controller	0nYYDDDF	4	Time stamp
Trackers	YYMMDD	6	Real date
Trackers	0nYYDDDF	4	Time stamp
Description databases	YYMMDD	6	Internal date
Batch loader and SYSIN for batch programs	YYMMDD	6	Real date
Dialogs and reports	Defined by the user, for example YY/MM/DD	8	Real date
Exits	YYMMDD	6	Real date
Exits	0nYYDDDF	4	Time stamp
Programming interfaces	YYMMDD	6	Defined by the user

Note:

Real date means that 1 January 1998 is represented as 980101.
For the internal date, IBM Z Workload Scheduler uses 1972 as the base year for the century window. This means that the year 1972 is represented as 00 and 2071 is represented as 99.
The z/OS time stamp uses 00YYDDDF for dates in the 20th century, and 01YYDDDF for dates in the 21st century.
The date format of the programming interfaces depends on the base year of the PIF century window defined by the PIFCWB keyword of the INTFOPTS statement, or the CWBASE keyword of the INIT statement. 00 implies real dates. 72 corresponds to theIBM Z Workload Scheduler internal date format.
