Download Description
PQ93024 resolves the following problem:

ERROR DESCRIPTION:
The WebSphere scheduler provides two calendaring functions to calculate task run dates. The CRON calendar allows specifying a string in a CRONTAB-like format to calculate possible dates.

There is an error in the scheduler CRON algorithm where the year may not be calculated.

For example:
Applying CRON expression: 0 0 0 1 1 ? to date 2004-08-15 10:00 will incorrectly producing a date with the current year: 2004-01-01 00:00. The correct date should be: 2005-01-01 00:00

LOCAL FIX:

USERS AFFECTED:
WebSphere Application Server Enterprise Edition 5.0.x users of the internal CRON calendar feature of the Scheduler function.

PROBLEM DESCRIPTION:
The CRON calendar may not increment the year.

RECOMMENDATION:
The WebSphere scheduler provides two calendaring functions to calculate task run dates. The CRON calendar allows specifying a string in a CRONTAB-like format to calculate possible dates. There is an error in the scheduler CRON algorithm where the year may not be calculated.

For example:
Applying cron expression: 0 0 0 1 1 ? to date: 2004-08-15 10:00 is incorrectly producing a date with the current year: 2004-01-01 10:00. The correct date should be: 2005-01-01 10:00

PROBLEM CONCLUSION:
The CRON calendar was fixed to increment the year properly.
