The DST42 timezone upgrade is now certified and available with Oracle E-Business Suite (EBS) Release 12.2.
DST patches are cumulative, and therefore include all previous Oracle DST updates.
How Does Oracle E-Business Suite Work Across Time Zones?
Periodically, a country or region changes its DST rules or timezone definitions. In addition, and more frequently, it may switch to or from Daylight Saving Time or Summer Time.
If your Oracle E-Business Suite environment is configured to support doing business across multiple time zones, you need to keep your timezone definition files up-to-date by applying patches as outline in this article. This will ensure that the times when transactions take place are recorded correctly, and thereby meet applicable business and legal requirements.
Is My Oracle E-Business Suite Environment Affected?
When a country or region changes its timezone definitions or DST rules, your Oracle E-Business Suite environment will require patching if either of the following is true:
Your EBS environment is located in the affected country or region.
Your EBS environment is located outside the affected country or region, but you conduct business or have customers or suppliers there.
What’s New?
The following are major additions or changes in the DSTv42 time zone definitions:
Egypt now uses DST again, from April through October.
This year Morocco springs forward April 23, not April 30.
Palestine delays the start of DST this year.
Much of Greenland still uses DST from 2024 on.
America/Yellowknife now links to America/Edmonton.
Prior to v42, the previous timezone upgrade certified with EBS was v41.
How Can I Identify and Apply the DST Patches I Need?
The following MOS note describes how to identify the various components in your EBS environment that may require DST patches, and provides full instructions on applying the patches:
Note: As of DSTv38, for ease of access the relevant tables in this MOS document list the latest EBS-certified patches at the top rather than the bottom.
What if Fail to Apply the Patches?
If your environment is affected as determined in Section 2 of MOS Note 563019.1, and you do not apply the relevant patches listed in Section 3, your EBS environment will not adhere to the new DST or Time Zone rules and transaction times may not be recorded correctly.
