void do_ftick (CHAR_DATA *ch, char *argument )
{
    update_handler( TRUE );
    send_to_char( "You Have Forced Time To Fly By....TICK\n\r", ch );
    return;
}

Put that part in act_wiz.c 

in update.c changce void update_handler to

void update_handler( bool forced )

And that should allow you to force ticks
