C语言time函数获取当前时间

以前放了个链接，但是原作者把博文删了，这里放一个获取时间的代码，已经比较详细所以不做注释

#include<stdio.h>
#include<time.h>
#include<stdint.h>
#include<stdlib.h>

int main()
{
	

	unsigned long long a = 0;
	char timeStr[14];


	time_t timer;
	struct tm *tblock;
	time(&timer);
	tblock = gmtime(&timer);


	a = (tblock->tm_year+1900)*100;
	a = (a+tblock->tm_mon+1)*100;
	a = (a+tblock->tm_mday)*100;
	a = (a+tblock->tm_hour+8)*100;
	a = (a+tblock->tm_min)*100;
	a = (a+tblock->tm_sec);
	sprintf(timeStr, "%llu", a);

	printf("现在时间是 %d 年 %d 月 %d 日 %d 时 %d 分 %d 秒.\n",\
			tblock->tm_year+1900, tblock->tm_mon+1, tblock->tm_mday,\
			tblock->tm_hour+8, tblock->tm_min, tblock->tm_sec);

	printf("a = %llu\n", a);
	printf("timeStr = %s\n", timeStr);
	return 0;
}

 运行结果
