why compile error???

archeror

my program:
[code:1]

#include <time.h>
#include <unistd.h>
int main()

{

time_t timep;
time (&timep);
printf("use asctime(gmtime(&timep)): %s\n", asctime(gmtime(&timep)));

printf("use ctime(&timep): %s timep is a varible of time_t. \n",ctime(&timep));

struct timevar tv;
struct timezone tz;

gettimeofday(&tv, &tz);

printf("tv_sec is %d\n", tv.tv_sec);
printf("tv_usec is %d\n", tv.tv_usec);
printf("tz_miniuteswest is %d\n", tz.tz_miniuteswest);
printf("tz_dsttime is %d\n", tz.tz_dsttime);

return 1;
}[/code:1]
use :  gcc -o testtime testtime.c
compile error message:
testtime.c: In function `main':
testtime.c:13: storage size of `tv' isn't known
testtime.c:14: storage size of `tz' isn't known

不认识你的timevar(我想是timeval) 和timezone(加include  <sys/time.h>。

果然是搞错了。多谢
