The DST v45 timezone updates are now certified and available with Oracle E-Business Suite (EBS) Release 12.2.
Daylight Saving Time (DST) patches are cumulative, and therefore include all previous Oracle DST updates.
How Does EBS Work Across Time Zones?
Periodically, many countries or regions change their DST rules or timezone definitions. In addition, and more frequently, they may switch to or from Daylight Saving Time or Summer Time.
If your EBS 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 outlined in this article. This will ensure that the times when transactions take place are recorded correctly, and thereby meet applicable business and legal requirements.
How Can I Determine if My EBS Environment Needs DST Patches?
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 with this Update?
The following are major additions or changes in the DST v45 time zone definitions:
Updates to daylight saving time (DST) transition rules for selected regions
Moldova (Europe/Chisinau) now follows European Union DST transition times
Alignment of time zone definitions with equivalent regions
Europe/Chisinau is aligned with Europe/Athens for future timestamp calculations
Introduction of new time zone definitions
Addition of America/Coyhaique to support regional requirements in Chile
Incorporation of the latest IANA time zone data updates
General improvements to time zone data accuracy and consistency
Enhances reliability of timestamp processing across affected regions
Prior to v45, the previous timezone upgrade certified with EBS was v44.
How Can I Identify and Apply the DST Patches I Need?
The following MOSFS Article describes how to identify the various components in your EBS environment that may require DST patches, and provides full instructions on applying the patches:
If your environment is affected as determined in Section 2 of MOSFS Article ID PNEWS2872, and you do not apply the relevant patches listed in Section 3, your EBS environment will not be compliant with the new DST or Time Zone rules and transaction times may not be recorded correctly.
