  "message": "[9.3.0] Record PackageZipper timestamps in the local time zone (from #30592) (#31180)\n\n### Description\n\n`PackageZipper` stamps every entry with a fixed instant of 1980-01-01\n00:00:00 UTC, but DOS timestamps carry no time zone. The recorded date\ntherefore depends on the zone of the machine that runs the tool.\n\nBehind UTC, that instant falls before the DOS epoch and is not\nrepresentable at all, which also affects Bazel\u0027s own build:\n\n```\nERROR: .../src/BUILD:293:13: Building src/package_jdk_minimal.zip failed: (Exit 1): package_zipper failed\nException in thread \"main\" java.lang.IllegalArgumentException: 1979-12-31 16:00:00 is not representable in the DOS time format. It must be in the range 1980-01-01 00:00:00 to 2107-12-31 23:59:59\n\tat com.google.devtools.build.zip.ZipUtil.unixToDosTime(ZipUtil.java:168)\n\tat com.google.devtools.build.zip.LocalFileHeader.create(LocalFileHeader.java:96)\n\tat com.google.devtools.build.zip.PackageZipper.writeBytesEntry(PackageZipper.java:212)\n```\n\nAhead of UTC the instant is representable, but records a later time of\nday: in `Europe/Berlin` the packed field is `0x00210800` (01:00:00)\nwhere a UTC machine writes `0x00210000` (00:00:00). The archive bytes\ndiffer by builder time zone, which defeats hermeticity.\n\nFixes #31165.\n\n### Motivation\n\n### Build API Changes\n\nNo\n\n### Checklist\n\n- [x] I have added tests for the new use cases (if any).\n- [ ] I have updated the documentation (if applicable).\n\n### Release Notes\n\nRELNOTES: None\n\nCloses #30592.\n\nPiperOrigin-RevId: 959815070\nChange-Id: Ib95a2cd9a0cbb40f1cc0a6264de3621e42045e2f\n\n\u003c!--\nThank you for contributing to Bazel!\nPlease read the contribution guidelines: https://bazel.build/contribute\n--\u003e\n\n### Description\n\u003c!--\nPlease provide a brief summary of the changes in this PR.\n--\u003e\n\n### Motivation\n\u003c!--\nWhy is this change important?
