It's Time to Talk About Time
summary
JavaScript gains a new Temporal API (stage three with a stage three polyfill) that replaces mutable Date with immutable Temporal objects, adds PlainDate/PlainTime/PlainDateTime/Duration/Instant/ZonedDateTime, and embeds the IANA time zone database so offsets reflect geopolitical DST rules. It offers duration math, rounding/balancing with a required relativeTo for years (handles leap years), comparators for sorting, and disambiguation modes around DST gaps/overlaps. It omits humanized strings and leap‑second handling.
