linux 获取日期及系统时间

    看linux程序设计的第四章-时间和日期,看到这个程序,感觉有点用,发到博客吧,不过有点小问题,运行时tm_hour的结果不正确,有待检查

 

#include<stdio.h>#include<time.h>#include<stdlib.h>int main(){    struct tm *tm_ptr;    time_t the_time;    (void)time(&the_time);    tm_ptr = gmtime(&the_time);    printf("date :%02d/%02d/%02d", tm_ptr->tm_year+1900, tm_ptr->tm_mon+1, tm_ptr->tm_mday);    printf(" %02d:%02d:%02d\n", tm_ptr->tm_hour, tm_ptr->tm_min, tm_ptr->tm_sec);    return 0;}
