The Instant jhost stored epoch-ms, so plusNanos/getNano rounded to the
millisecond and two instants a nanosecond apart compared =. Store epoch-nanos
instead: mk-instant still takes ms (scales to nanos) for the ms-based zone/Date
callers, mk-instant-nanos/inst-nanos own the nano arithmetic, and inst-ms floors
nanos back to ms. plus/minus/getNano/truncatedTo/compare/equals and the ISO
renderer all run on nanos; toString shows the fraction in 3/6/9-digit groups like
ISO_INSTANT. Fixes tick's interval coincidence test (shift end by one nano).
ZoneOffset/ZoneId (SHORT_IDS, fixed-offset + UTC + system; named zones via a
fixed-offset table), ZonedDateTime/OffsetDateTime/OffsetTime, Clock (fixed/
system, with now [clock] arity), and DateTimeFormatter integration (ofPattern
+ ISO_* constants, .format/.parse over the rich java.time values via the
inst-time.ss pattern engine). systemDefault resolves to UTC to keep the
#inst atZone/toInstant round-trip machine-tz-independent.
tick.core + tick.protocols + tick.locale-en-us load; tick's api_test runs
31 tests / 352 pass / 7 fail / 0 error. The 7 are host gaps: named-zone DST
(no tzdb), French locale month names (no locale DB), nanosecond Instant.
General fixes surfaced by tick: :ns/keys map destructuring ({:tick/keys [..]})
in 00-syntax.clj (re-minted), and extend-protocol to java.time classes
(records.ss host-type-set). 12 corpus rows certified vs JVM. make test +
shakesmoke green, selfhost holds, 0 new divergences, data.json stays 138/139.
Duration (ISO PT.. toString, between, full arithmetic), Period (between with
borrow, P.. toString, normalized), full Month/DayOfWeek enums (named constants,
print as their name — fixes the Phase-1 raw-jhost print), Year, YearMonth
(2020-02 toString, leap, atDay/atEndOfMonth), ChronoUnit (between/getDuration)
and ChronoField. The temporal machinery on the Phase-1 types now works with
ChronoUnit/ChronoField: (.plus t n DAYS), (.until t1 t2 unit), (.get/.getLong
t field), (.with t field v), (.isSupported ..), (.truncatedTo ..).
Analyzer: (. Class method args) with a class target lowers to a static call
(Class/method args) instead of mis-dispatching as an instance call on the arg
— matches JVM; needed by cljc.java-time.year. Seed re-minted; selfhost holds.
The Phase-2 cljc.java-time namespaces load; tick.core advances to a Phase-3
zone gap. 10 corpus rows certified vs JVM. make test + shakesmoke green, 0 new
divergences, data.json stays 138/139.
Core java.time value types as jolt host objects backed by the inst-time.ss
calendar engine (days-from-civil/civil-from-days/inst-fields/format-ms), in a
new host/chez/java-time.ss. tz-free reps: LocalDate=epoch-day,
LocalTime=nano-of-day, LocalDateTime=(epoch-day,nano-of-day); Instant reuses
the ms-based instant jhost (ms granularity; nano is a documented gap). Each
type registers statics (of/parse/now/MIN/MAX/...), instance methods
(plus/minus/with/get/isBefore/until/toString/...), =/hash, compare,
ISO-8601 print, instance?, and value-host-tags for protocol dispatch.
Reconciles the old ms-based local-date/local-dt stubs into the rich types
(LocalDateTime now prints ISO; .toLocalDate/.atZone paths preserved). The
four cljc.java-time namespaces (local-date/local-time/local-date-time/instant)
load. Deep temporal-field/unit machinery (range/get-long/with-field/until/
adjust-into) stubbed for Phase 2.
12 corpus rows certified vs JVM 1.12.5. make test + shakesmoke green, 0 new
divergences, data.json stays 138/139, selfhost holds.
