Struct LocalTimeZone 

pub struct LocalTimeZone { /* private fields */ }

An immutable local-time resolver.

Materialized system resolvers own the complete time-zone rule set rather than the offset sampled at “now”: another target date may be on the other side of a daylight-saving transition. The captured rules and their lazily computed provenance are shared by every clone of a resolver.

Wide civil dates remain project-owned. Jiff is used only as the system time-zone rule engine; dates outside Jiff’s civil range are projected onto a Gregorian-equivalent year before rules are queried and are then mapped back without narrowing the represented instant.

Implementations

impl LocalTimeZone

pub fn fixed(offset_minutes: i32) -> Result<Self, RuntimePolicyError>

pub fn utc() -> Self

pub fn try_system() -> Result<Self, RuntimePolicyError>

Captures the system time-zone rules or reports that the adapter is unavailable.

pub fn provenance(&self) -> &LocalTimeZoneProvenance

pub fn is_system(&self) -> bool

pub fn fixed_offset_minutes(&self) -> Option<i32>

pub fn resolve_local(&self, local: CivilDateTime) -> Option<OffsetDateTime>

Resolves a local civil date-time using this resolver’s compatible DST policy.

Gaps move forward by the gap duration and folds select the earlier instant, matching Mermaid’s JavaScript date behavior and Jiff’s compatible disambiguation.

pub fn at_instant(&self, unix_millis: i64) -> Option<OffsetDateTime>

Applies this resolver’s offset rules to an absolute millisecond instant.
