public class CurrentDatetime {

    public static void main(String[] args) {

        // 纪元秒和本地日期时间互换

        Instant epochSec = Instant.ofEpochSecond(1000000000L);

        ZoneId zId = ZoneId.systemDefault();

        ZonedDateTime then = ZonedDateTime.ofInstant(epochSec, zId);

        System.out.println("The epoch was a billion seconds old on " + then);

    }

}

运行输出：

The epoch was a billion seconds old on 2001-09-09T09:46:40+08:00[Asia/Shanghai]
