Yeah right. Stop posting questions from the web.

This is an idiotic PM question. Not a developer question.

Create a watch alarm clock that vibrate :)

#include <stdio.h>
#include <time.h>

int main(void) {

time_t rawtime;
struct tm* time_;

time(&rawtime);
time_ = localtime(&rawtime);

printf("%i:%i:%i %i %i %i\n", time_->tm_hour, time_->tm_min,
time_->tm_sec, time_->tm_mday, time_->tm_mon+1,
time_->tm_year+1900);

return 0;
}
