ThreeTen (JSR 310) the new Date and Time API in Java 8
summary
JSR 310 / ThreeTen is a Joda Time–based Date/Time API for Java 8 that splits time into a machine model (Instant, Duration) and a human model (LocalDate, LocalTime, ZonedDateTime), adds a Clock abstraction for testable current time, and fixes DST and leap-year edge cases (e.g. adding one month from Jan 31 yields Feb 28). Examples show converting OffsetDateTime to Instant for precise arithmetic, constructing fixed Clocks for tests, and the recommendation to use Joda now and migrate to ThreeTen/Java 8.
