This PR adds support for the std/dstOffset attributes in CLDR metazone definitions. These attributes were introduced in CLDR v48 to address differences between the IANA TZDB vanguard and rearguard formats. At the time JDK adopted CLDR v48, this support was not implemented because the JDK handles these differences separately (see JDK-8212970).
More recently, the America/Vancouver time zone is planning to adopt a year-round fixed offset. To avoid mismatches between standard and daylight saving time naming, CLDR has started using these attributes for that zone. This change prepares the JDK for upcoming TZDB updates and the corresponding CLDR changes. ------------- Commit messages: - import fixup - initial commit Changes: https://git.openjdk.org/jdk/pull/30594/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30594&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8381379 Stats: 94 lines in 8 files changed: 73 ins; 7 del; 14 mod Patch: https://git.openjdk.org/jdk/pull/30594.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30594/head:pull/30594 PR: https://git.openjdk.org/jdk/pull/30594
