* Use chrono for UTC/calendar conversion instead of hand-rolled copies Replaces the hand-rolled Howard Hinnant civil/days-from-civil copies and the leap-year/days-in-month table with chrono as a workspace dependency: - apps/lightcraft/src/logging.rs: timestamp (log line time) - crates/catalog/src/dates.rs: civil + weekday - crates/catalog/src/stacks.rs: iso_seconds (date -> seconds) - crates/engine/src/cmd/face_recognize.rs: capture_secs (native only) - crates/meta/src/datetime.rs: DateTime::unix_seconds and the valid() day check Output formats and semantics are unchanged (pre-epoch clamp, day rollover that normalize_iso relies on, leap-second tolerance, EXIF/XMP parsing). chrono uses only std, so wasm stays safe. AGENTS.md/CLAUDE.md now say time goes through chrono. Follow-up to storytold/cadcraft#1785 * Never panic on a clock outside chrono's range; keep 5-digit years unprefixed chrono's From<SystemTime> unwraps, so a clock past year 262143 panicked inside the logger. timestamp now uses the fallible DateTime::from_timestamp and reads such a clock as the epoch, keeping the old pre-epoch clamp. timestamp and catalog's civil write years past 9999 with {:04} like the old {y:04} did, because %Y would add a '+'. Tests cover the out-of-range and 5-digit-year cases. * Don't build an unrepresentable SystemTime in the far-future test UNIX_EPOCH + Duration::from_secs(u64::MAX / 2) overflows Windows' SystemTime and panicked before timestamp() ran, failing the Windows test job. Build it with checked_add and only assert where it exists. * time: preserve old out-of-range date conversion (no epoch fallback) `DateTime::from_timestamp(...).unwrap_or_default()` silently reset any instant past chrono's year range to 1970-01-01, changing output the old hand-rolled Howard-Hinnant code converted exactly (e.g. 10_000_000_000_000 s was 318857-05-20 17:46:40, not the epoch). Restore the old conversion domain with a cycle-based helper that routes the calendar through chrono (the calendar repeats every 400 years = 146_097 days, so month/day/time come from chrono and only the year is carried in i128, keeping every i64 exact). - apps/lightcraft/src/logging.rs: `timestamp` via `utc_parts`; keep the pre-1970 epoch clamp; u64 secs past i64::MAX saturate, not epoch. - crates/catalog/src/dates.rs: `civil` cycle-based (the callers stay inside 0000-9999, but a far clock no longer resets to the epoch). Pinned old outputs in tests: logging u64::MAX/2 s -> 292277026596-12-04T15:30:07.000Z (was epoch), 10_000_000_000_000 s -> 318857-05-20T17:46:40.000Z civil 10_000_000_000_000 -> 318857-05-20T17:46:40, -10_000_000_000_000 -> -314918-08-13T06:13:20, i64 extremes * Don't build a year-318857 SystemTime unchecked in the logging test Windows' SystemTime only reaches about year 30828, so UNIX_EPOCH + Duration::from_secs(10_000_000_000_000) panicked before timestamp() ran and failed the Windows test job. Build it with checked_add and assert where the platform can hold it. The year-10000 case fits everywhere and stays unconditional. * Name the 400-year range extension as the one exception to the time rule The rule said never to hand-roll calendar math, but the range fix (shifting by whole 400-year Gregorian cycles so dates past chrono's year range keep their old output) is cycle arithmetic, so the rule and the code disagreed. The rule now names that exception: the library still computes month, day and time, and only whole cycles are carried in the year. * Say the library computes month and day; time-of-day is plain arithmetic Narrows the range-extension wording: the date library computes the calendar fields, and splitting seconds into hours, minutes and seconds is ordinary arithmetic, which is what the code does.
