近来有很多童鞋渴望来一场激烈的CF（是Codeforces不是Cross Fire）来提升自己的实力，但是大家都知道，codeforces上公布的比赛时间都是UTC时间（协调世界时），可是没有关系，我们可以写一个小工具来方便完成时间转化。

 只要知道UTC time与Beijing time的转换关系，我们轻松完成这一转换任务（UTC time + 8 hours = Beijing time）

通过我们的转换小工具

 

Code 

//UTC-time + 8 hours = Beijing-time#include <iostream>#include <cstdio>using namespace std;int year, month, day, hour, minute;int mon[] = {0, 31, 28, 31, 30, 31, 30, 31, 30, 30, 31, 30, 31};bool LeapYear(int y){if ((y % 4 == 0 && y % 100 != 0) || (y % 400 == 0)) return true;else return false;}void solve(){if (LeapYear(month)) mon[2] = 29;else mon[2] = 28;if (hour == 24 && minute != 0){day += 1;hour = 0;}else if (hour > 24){day += 1;hour -= 24;}if (day > mon[month]){day -= mon[month];month += 1;}if (month > 12){year += 1;month -= 12;}}int main(){printf(" ---------------------------------------\n");printf("|请输入您从Codeforces上获取的UTC比赛时间|\n");printf("| 输入格式严格按照如下格式输入 |\n");printf("| 月/日/年(12/09/2018) |\n");printf("| 小时/分钟(16:05) |\n");printf(" ---------------------------------------\n");printf(">> ");scanf("%d/%d/%d", &month, &day, &year);printf(">> ");scanf("%d:%d", &hour, &minute);//printf("UTC-time：%d/%d/%d %02d:%02d\n", month, day, year, hour, minute);hour += 8;solve();printf("<< Beijing Time：%d/%d/%d %02d:%02d\n", month, day, year, hour, minute);return 0;}
