Faithful Rust port of IANA tzdb checklinks.awk — Zone/Link graph consistency checker (link-to-nowhere, link-to-link, name collisions, backward backcheck)

A high-performance Python library for parsing and analyzing the IANA Time Zone Database (tzdb). Built for production use with smart caching, minimal dependencies, and a practical API.

Faithful, memory-safe Rust port of upstream tzselect.ksh — the interactive IANA tzdb timezone selector. Byte-identical prompt/output parity vs the shell oracle.

External QEMU/vendor-oracle evidence lab for zic-rs cross-platform zic/zdump receipts and VM lineage data.

Faithful, memory-safe Rust port of upstream leapseconds.awk — generates the zic 'leapseconds' source from NIST/IERS leap-seconds.list, byte-identical to the awk oracle.

A memory-safe Rust IANA zic / TZif compiler

Faithful, memory-safe Rust port of upstream tzcode date.c — the small standalone 'tzdate' utility. Verified against the compiled tzcode oracle. Not a date/time library.

Bounded Rust TZif witness and zdump-compatible inspection companion for zic-rs evidence workflows.
