C语言_时间日期函数

以下代码为获取系统当前时间

#include <stdio.h>#include <stddef.h>#include <time.h>int main(void){time_t timer;//time_t就是long int 类型struct tm *tblock;timer = time(NULL);tblock = localtime(&timer);printf("Local time is: %s\n",asctime(tblock));return 0;}

#include<time.h>#include<stdio.h>int main(){struct tm *t;time_t tt;time(&tt);t=localtime(&tt);printf("%4d年%02d月%02d日 %02d:%02d:%02d\n",t->tm_year+1900,t->tm_mon+1,t->tm_mday,t->tm_hour,t->tm_min,t->tm_sec);return 0;}
