feat!: replace chrono/chrono-tz with jiff behind newtypes#80
Merged
Conversation
BREAKING CHANGE: Value/QueryParam date variants now use rsmgclient-owned Date/LocalTime/LocalDateTime/Duration newtypes instead of chrono::Naive*/ Duration. jiff is a private implementation detail, so future datetime-backend swaps stay non-breaking. - drop chrono + chrono-tz deps; add jiff (bundles tzdb, no separate tz crate) - mg_value_datetime_zone_id now resolves the instant in its IANA zone via jiff TimeZone instead of manual chrono-tz offset math - Duration wraps jiff SignedDuration (flat duration, matching prior semantics) - Display output preserved (LocalDateTime space separator, Duration PT..S) Note: zoned DateTime now reports zone-local wall-clock fields (previously UTC fields + separate offset); identical for UTC, corrected for other zones.

The chrono/chrono-tz -> jiff migration (#80) changes public Date, LocalTime, LocalDateTime, and Duration types, which is a breaking change for consumers matching or constructing those variants.

@andrejtonev , you have to release current master, then merge thus one and bump the version for this one.
Existing users will have to update their code, but get 1 less dependency and a more correct crate than chrono.
Future time backend changes will not break the contract as this crate own it.
