Java Data Type - 如何从时钟创建本地日期时间

import java.time.Clock;
import java.time.LocalDateTime;

public class Main {
  public static void main(String[] args) {
    // Current Time
    Clock clock = Clock.systemUTC();
    System.out.println(Clock.systemDefaultZone());

    LocalDateTime dateAndTime = LocalDateTime.now(clock);
    System.out.println(dateAndTime);
    System.out.println(LocalDateTime.now());

  }
}
