What Patches Are Required?
In case you haven't been following our previous time zone or Daylight Saving Time (DST)-related articles, international timezone definitions for E-Business Suite environments are captured in a series of patches for the database and application tier servers in your environment. The actual scope and number of patches that need to be applied depend on whether you've applied previous DST or timezone-related patches. Some sysadmins have remarked to me that it generally takes more time to read the various timezone documents than it takes to apply these patches, but your mileage may vary.
Proactive backports of DST upgrade patches to all Oracle E-Business Suite tiers and platforms are not created and supplied by default. If you need this DST release and an appropriate patch is not currently
available, raise a service request through support providing a business case with your version requirements.

Our certification of this DST timezone patch with Oracle E-Business Suite 12.2 is currently underway.
Oracle's Revenue Recognition rules prohibit us from discussing certification and release dates, but you're welcome to monitor or subscribe to this blog. I'll post updates here as soon as soon as they're available.
