linux下怎样用c语言编写一个时钟

我希望你只是需要如何知道时间，而不是写你一个时钟程序，那个太复杂了，如果只是想如何知道时间-

#include stdio.h

#include time.h

int main(void)

{

struct tm *tm_ptr;

time_t the_time;

(void)time(the_time);

tm_ptr=localtime(the_time);

printf(“Date: %04d/%02d/%02d\n”,

1900+tm_ptr-tm_year,tm_ptr-tm_mon+1,tm_ptr-tm_mday);

printf(“Time: %02d:%02d:%02d\n”,

tm_ptr-tm_hour,tm_ptr-tm_min,tm_ptr-tm_sec);

return(0);

}
