Module dates 

Civil-date ↔ FILETIME conversion for dm: filters.

dm: bounds are interpreted in the local time zone (docs/ARCHITECTURE.md C-4). The conversion is injected via DateResolver so the parser/compiler stay pure and tests can use UTC.

Structs

Civil

A proleptic Gregorian calendar date with no time-of-day or zone.

UtcResolver

Pure UTC resolver — deterministic, used by unit tests.

WindowsLocalResolver

Local-time-zone resolver backed by the Windows time-zone/DST rules.

Constants

FILETIME_UNIX_EPOCH

FILETIME ticks (100 ns since 1601-01-01) at the Unix epoch (1970-01-01).

TICKS_PER_SECOND 🔒

Traits

DateResolver
