http://site.icu-project.org. (PRPC does not directly use Java libraries from the International Components for Unicode (ICU) project; it relies on Java code in each vendor's JVM.)A part of the Unicode standardization effort, the Common Locale Data Repository (CLDR) provides foundation building blocks to support date and time formats by locale.
PRPC 5.3 and later implements the Unicode CLDR 1.3 standards for date and time patterns by locale and other internationalization features. Details of locale names, time zone names, and daylight savings time support depend on the JVM version supporting your system.
For background and details on this standard, see http://site.icu-project.org. (PRPC does not directly use Java libraries from the International Components for Unicode (ICU) project; it relies on Java code in each vendor's JVM.)
Releases of PRPC before 5.3 used an IBM ICU4J library rather than the CLDR 1.3 standard. If you upgrade an older system to 5.3 or later, follow instructions in the Upgrade Guide regarding the pricu2jdk.jar file.
