Time Zone Normalization

When SMF data is processed, SMF uses the timestamp in the record. That timestamp reflects the time zone where the record was produced (called EXEC time) and may or may not match the time zone of the CA Workload Automation SE where the job is processed (called CA7 time). This mismatch may cause jobs to appear out of sequence, or a data set creation time may be later than the system current time.

The time zone normalization (TZN) enhancement keeps track of time zones and data in certain SMF extract records and some log records. The data kept is the Time Zone Offset (TZO) of the system in which the job executed. TZO is the difference between that system's time zone and Coordinated Universal Time (UTC), which is also called Greenwich Mean Time (GMT).

When TZN processing is in effect, the execution time zone offset (EXEC TZO) is compared with the CA Workload Automation SE time zone offset (CA7 TZO). If there is a difference, the execution time is normalized to the CA Workload Automation SE time. TZO is not the difference between EXEC time and CA7 time.

Execute the /DISPLAY,ST=CA7 command to display the CA7 TZO. The results of the following commands can show TZN data: LCTLG, LDSN, LJOB, LPRRN, LQ, and LRLOG.

Note: For more information, see the Command Reference Guide.

The following SASSHIS8 reports can contain TZN data: HR04, HR06, HR09, HR13, and HR50. Report control statements have changed to report either CA7 time or EXEC time.

Note: For more information, see the Report Reference Guide.

A new statement, SMF, has been added to the initialization file. For TZN, the SMF statement has the following two new keywords:

TZDISPLAY=EXEC|CA7: Specifies the default option for those commands that have a TZ= keyword. The TZ= keyword is new to the previously mentioned commands.
TZPREDS=EXEC|CA7: Specifies the time zone used to satisfy the lead (look back) time that can be used to satisfy initial requirements when a job enters the request queue.

Because EXEC is the current method of operation, both TZDISPLAY and TZPREDS default to operate in the same manner as pre-r11.3 releases. The TZO data is maintained in the records regardless of the keyword settings.
