hi brother!
your code is wrong!
plaese see  here(right code):

#include <time.h>
int main(int argc, char *argv[])
{  char strt[150];
   time_t  tp;
  char *str;
  time(&tp);
  str=strt;
  str=ctime(&tp);
  printf("time is %s",str);
}

you must get basic technique of coding!

呵呵，英语太差了，寒自己一个！

不好意思，出现疏忽，不过依然不能用time函数呀

ccjjhua

char SYSTEMTIME[15];
char *getsystemtime()
{
  time_t timer;
  struct tm *tblock;

  memset(SYSTEMTIME,0,sizeof(SYSTEMTIME));
  timer=time(NULL);
  tblock=localtime(&timer);
  sprintf(SYSTEMTIME,"%04d%02d%02d%02d%02d%02d",tblock->tm_year+1900,tblock->tm_mon+1,tblock->tm_mday,tblock->tm_hour,tblock->tm_min,tblock->tm_sec);
  return SYSTEMTIME;
}
