创建一个Instant,并使用从1970-01-01T00:00:00Z的纪元作为参数传递的毫秒数来获取Instant。使用ofEpochMilli()以下命令完成此操作:
Instant instant = Instant.ofEpochMilli(342627282920l);
现在,从即时获取时代纪元:
instant.getEpochSecond();
import java.time.Instant;
public class Demo {
public static void main(String[] args) {
Instant instant = Instant.ofEpochMilli(342627282920l);
long res = instant.getEpochSecond();
System.out.println(res);
}
}输出结果
342627282
