Module model 

The parsed, still-textual semantic model of a tzdata source: the records the parser produces and the compiler consumes.

These types mirror the three tzdata line kinds (Rule, Zone, Link) plus the continuation structure of zones. They are intentionally close to the source — value interpretation (calendar math, transition generation) happens later, in compile.

Modules

calendar

Proleptic Gregorian calendar arithmetic, implemented in-house.

leap

The leap-second table model (T11) — a distinct time model, not a transition stream.

time

Parsing of tzdata time-ish fields: UT offsets (STDOFF), saved amounts (SAVE and inline rules), and times-of-day (AT, and the time part of UNTIL).

Structs

Database

The whole parsed source: zones, links, and rules keyed by name.

LinkRecord

A Link line: LINK-NAME is an alias for TARGET.

Origin

Where a record came from, for diagnostics.

RuleRecord

A Rule line. Stored verbatim-ish in T1 (only validated, not yet expanded); the transition compiler in T2 consumes the typed fields.

Until

The UNTIL field: a partially-specified wall/standard/UT instant.

ZoneEra

One era of a zone (one Zone/continuation line up to its UNTIL).

ZoneRecord

A Zone plus its continuation lines.

Enums

YearBound

Upper bound of a rule’s year range.

ZoneRules

The RULES column of a zone era.
