Instant可以创建遗留的java.util.Date 对象。 Clock provides access to the current date and time. Clocks are aware of a timezone and may be used instead of System.currentTimeMillis() to retrieve the current time in milliseconds since Unix EPOCH. Such an instantaneous point on the time-line is...
Such an instantaneous point on the time-line is also represented by the class Instant. Instants can be used to create legacy java.util.Date objects.Clock clock = Clock.systemDefaultZone(); long millis = clock.millis(); Instant instant = clock.instant(); Date legacyDate = Date.from(instant...
