Java程序从时钟创建LocalDateTime
首先，设置时钟：
Clock clock = Clock.systemUTC();
现在，创建LocalDateTime：
LocalDateTime dateTime = LocalDateTime.now(clock);
示例
import java.time.Clock;
import java.time.LocalDateTime;
public class Demo {
public static void main(String[] args) {
Clock clock = Clock.systemUTC();
System.out.println("Clock = "+Clock.systemDefaultZone());
LocalDateTime dateTime = LocalDateTime.now(clock);
System.out.println("LocalDateTime = "+dateTime);
}
}输出结果
Clock = SystemClock[Asia/Calcutta] LocalDateTime = 2019-04-19T09:29:50.605820900
