Surely you are doing something wrong. time() works on every
conforming C and C++ implementation in existence.
I just built and ran this console application on VS2005 beta 2 (I
haven't gotten around to removing it and installing the release
version):
#include <stdio.h>
#include <time.h>
int main(void)
{
time_t time1 = time(NULL);
struct tm time2 = *localtime(&time1);
printf("%s\n", asctime(&time2));
return 0;
}
And here is the output in the console window:
Mon Jan 02 15:03:18 2006
Press any key to continue . . .
So if time() does not work for you, there is something wrong with your
installation or your program.
