Please log a SR if you need a backport to a platform or current version not released yet.

NO Proactive backports of the OJVM DSTv24 <patch 20875943> are done. All supported versions can be requested .
Please log a SR if you need a backport . Note that the OJVM DST patch is platform generic.

There are no "PSU DST patches" , for example an Oracle DST patch for 11.2.0.4 can be applied using Opatch on *any* 11.2.0.4 psu (same goes for any other Oracle RDBMS version)

Note that backports to versions who are NOT in Premier Support are possible / available for download only for customers with a valid Extended Support .
Exceptions for other version/platform combination are only possible for customers with an existing Extended Support contract for the specific version/platform combination or platforms with Extended Support Fee Waiver Period.
Please log a SR if you need a backport to such an platform / version (if you need several log 1 sr clearly stating which version/platforms you have Extended Support contract for and need ).
See <Note 412160.1> , section "G) For what versions are DST patches provided / there is no DST version X for my Oracle RDBMS version?"
Please consult your Sales representative to enroll in an Extended Support contract if required.
If you log a SR requesting a backport or the password for versions in Extended Support and there is no Extended Support contract in place the patch cannot be provided.

The RDBMS DSTv24 update includes the timezone information from the IANA ( http://www.iana.org/time-zones ) data tzdata2015d.tar and contains all previous Oracle RDBMS DST updates.
The OJVM DSTv24 update includes the timezone information from the IANA (http://www.iana.org/time-zones ) data tzdata2015d.tar and contains all previous Oracle OJVM DST updates.

This is archived content. The note covers the "DSTv24" update, newer DST updates are available.
Please see <Note 412160.1> Updated Time Zones in Oracle Time Zone File patches for information on the newer DST patches.

An complete overview of timezone updates is found in <Note 412160.1> Updated DST transitions and new Time Zones in Oracle Time Zone File patches.
 
Compared to DSTv23 this is the list of updated timezones in DSTv24 for non historical dates ( meaning update to the timezone after 1970):

Africa/Cairo, America/Cancun, America/Grand_Turk, America/Santiago, Antarctica/Palmer, Asia/Dacca, Asia/Hovd, Asia/Ulaanbaatar, Asia/Gaza, Asia/Choibalsan, Asia/Hebron, Europe/Minsk, Pacific/Easter, Pacific/Fiji, Egypt, Jamaica, Chile/Continental, Asia/Dhaka, Asia/Ulan_Bator, Chile/EasterIsland .

Scope

This note will give an overview on what checks to perform before applying the DSTv24 update.
Note that all DST patches are always cumulative, which means they contain also ALL the previous DST changes / corrections.

Please note that SYSDATE is NOT affected by "Oracle DST patches" seen SYSDATE is purely depending on the OS to get the time.
So even an "unpatched database" will return a correct SYSDATE if the server (OS) time is correct.
For "sysdate" you do not need any DST patch  <note 1627439.1> How to diagnose wrong time ( SYSDATE and SYSTIMESTAMP) after DST change , server reboot , database restart or installation when connecting to a database on an Unix server
For more information about Timestamp with (local) Time Zone please check <Note 340512.1> Timestamps & time zones - Frequently Asked Questions
