我也想问，为什么我用Java的 `LocalDateTime` 跑出来的结果比样例秒数少1
```java
import java.io.*;
import java.time.LocalDateTime;
import java.util.*;
public class Main {
static BufferedReader buf = new BufferedReader(new InputStreamReader(System.in));
static PrintWriter cout = new PrintWriter(new BufferedWriter(new OutputStreamWriter(System.out)));
static StreamTokenizer st = new StreamTokenizer(buf);
public static int nextInt() throws IOException {
st.nextToken();
return (int) st.nval;
}
public static String nextLine() throws IOException{
String line = buf.readLine();
while(line.isEmpty()) line = buf.readLine();
return line;
}
static int n,m,k,l;
static int[] head,vis;
static int cnt=0,tot=0;
static final int INF = 0x3f3f3f3f;
public static void main(String[] args) throws IOException {
int t = nextInt();
while(t-->0){
n = nextInt();
int totSe = (int)Math.pow(2,n-1)-1;
int year = nextInt();
int month = nextInt();
int day = nextInt();
int hour = nextInt();
int minute = nextInt();
int second = nextInt();
LocalDateTime base = LocalDateTime.of(year, month, day, hour, minute, second);
base = base.plusSeconds(totSe);
cout.printf("%d %d %d %d %d %d\n",base.getYear(),base.getMonth().getValue(),
base.getDayOfMonth(),base.getHour(),base.getMinute(),base.getSecond());
}
cout.flush();
}// End of main
}
```
