xp下c语言获取系统日期及时间

一：下面是经常在c语言中用的用于获取系统的时间,在vc中也可以使用.

#include <stdio.h>

#include <time.h>
void main()
{
time_t timep;
struct tm *p;
time(&timep);
p=gmtime(&timep);
printf("%d\n",p->tm_sec); 
printf("%d\n",p->tm_min); 
printf("%d\n",p->tm_hour+8);


printf("%d\n",1900+p->tm_year);
printf("%d\n",p->tm_mday);
printf("%d\n",p->tm_mon+1);
char date[10];


if (((p->tm_mon+1)<10) && ((p->tm_mday)<10))
{
sprintf(date,"%d0%d0%d",1900+p->tm_year,p->tm_mon+1,p->tm_mday);
}
else if(((p->tm_mon+1)<10) && ((p->tm_mday)>9))
{
sprintf(date,"%d0%d%d",1900+p->tm_year,p->tm_mon+1,p->tm_mday);
}
else if (((p->tm_mon+1)>9) && ((p->tm_mday)<10))
{
sprintf(date,"%d%d0%d",1900+p->tm_year,p->tm_mon+1,p->tm_mday);
}
else
{
sprintf(date,"%d%d%d",1900+p->tm_year,p->tm_mon+1,p->tm_mday);
}
printf("%s\n",date);


char ti[10];
sprintf(ti,"%d:%d:%d",p->tm_hour+8,p->tm_min,p->tm_sec);
printf("%s",ti);

}

二：下面是vc++经常用来获取系统的时间

COleDateTime time = COleDateTime::GetCurrentTime();
CString addTime = time.Format("\n%Y-%m-%d %H:%M:%S\n");
