让我们首先设置一个Instant:
Instant now = Instant.ofEpochMilli(184142540078l);
现在让我们减去Instant的秒数:
Instant resSeconds = now.minusSeconds(50);
现在让我们减去Instant的十亿分之一秒:
Instant resNanoSeconds = now.minusNanos(10000);
import java.time.Instant; public class Demo { public static void main(String[] args) { Instant now = Instant.ofEpochMilli(184142540078l); System.out.println(now); Instant resSeconds = now.minusSeconds(50); System.out.println("After subtracting seconds = "+resSeconds); Instant resNanoSeconds = now.minusNanos(10000); System.out.println("After subtracting nanoseconds = "+resNanoSeconds); } }
输出结果
1975-11-02T06:42:20.078Z After subtracting seconds = 1975-11-02T06:41:30.078Z After subtracting nanoseconds = 1975-11-02T06:42:20.077990Z
