IIUC, cc65 tries to make as few assumptions as possible about the 
destination environment. If you know you're headed for Apple II, ProDOS 
and Basic, this works by synchronizing the I/O hooks:

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

int main (void) {

    time_t starttime = time(NULL);
    time_t endtime = time(NULL);

    /* Assume 80-column card, ProDOS, Basic */
    __asm__ ("jsr %w", 0xc300);
    __asm__ ("lda %b", 0x36);
    __asm__ ("sta %w", 0xbe30);
    __asm__ ("lda %b", 0x37);
    __asm__ ("sta %w", 0xbe31);
    __asm__ ("lda %b", 0x38);
    __asm__ ("sta %w", 0xbe32);
    __asm__ ("lda %b", 0x39);
    __asm__ ("sta %w", 0xbe33);

    /* Clear the screen, put cursor in upper left corner */
    clrscr ();

    printf("Start time: %s\n",asctime(localtime(&starttime)));
    printf("  End time: %s\n",asctime(localtime(&endtime)));

    return EXIT_SUCCESS;
}

Printing control-D PR#3 doesn't appear to work.
