C语言获取系统时间再按格式输出

代码如下：

#include
#include
#include
#include 

int main()
{
	time_t timep;
	struct tm *p;

	//获取时间
	time (&timep);
	p=gmtime(&timep);

	//存储时间
	char s[2],m[2],h[2],d[2],mon[2],year[4],total[19];

	//int转char
	sprintf(s,"%02d",p->tm_sec);
	sprintf(m,"%02d",p->tm_min);
	sprintf(h,"%02d",8+p->tm_hour);
	sprintf(d,"%02d",p->tm_mday);
	sprintf(mon,"%02d",1+p->tm_mon);
	sprintf(year,"%04d",1900+p->tm_year);

	//字符串拼接，按照yyyy-mm-dd hh:mm:ss的格式输出（共19个字符）
	strcat(total,year);
	strcat(total,"-");
	strcat(total,mon);
	strcat(total,"-");
	strcat(total,d);
	strcat(total," ");
	strcat(total,h);
	strcat(total,":");
	strcat(total,m);
	strcat(total,":");
	strcat(total,s);
	
	printf("%s\n",total);
	return 0;
}

运行结果：
