Introducing kotlinx-datetime
summary
kotlinx-datetime v0.1 is a multiplatform date/time library (Kotlin/JVM 8+, JS, Native) that implements immutable types—Instant, LocalDate/LocalDateTime—and clear conversion rules with TimeZone handling and DST strategies. It provides Duration, DateTimeUnit (custom multiples), periodUntil/daysUntil/monthsUntil, and conversion bridges to java.time and Foundation. Roadmap items include kotlinx.serialization integration, basic English formatting/parsing, ranges/progressions, and an embeddable TZDB for consistent timezone rules.
