The change was in [the 24u commit](https://git.openjdk.org/jdk24u/commit/81252ef76899ad95197550a11c2786ccf3cf0cd2) which was applied later than the 21u one.

JDK 21 file path is `src/java.base/share/data/tzdata/zone.tab`
JDK 17 file path is `make/data/tzdata/zone.tab`

Change to the file itself is the same. Looks good.
