简单实现vc上显示系统当前时间

#include<stdio.h>
#include<time.h>
#include<windows.h> //Sleep(毫秒)函数 sleep(秒)

int main(int argc ,char *argv[])
{
    time_t time_second = { 0 };
    unsigned int year=0, month=0, day=0, hour=0, minute=0, second=0;
    char LocalTime[100] = { 0 };
    struct tm *t0 ;
    time_second = time(NULL); //返回秒
    t0 = localtime((const time_t*)&time_second);
    year =   t0->tm_year + 1900;
    month =  t0->tm_mon + 1;
    day =    t0->tm_mday;
    hour =   t0->tm_hour;
    minute = t0->tm_min;
    second = t0->tm_sec;
    sprintf(LocalTime, "%d-%02d-%02d %02d:%02d:%02d", year, month, day, hour, minute, second);
    printf("LocalTime = %s\n",LocalTime);

    return 0;
}
