Help with cronjob command line

You are asking it to be less than when the day starts, and greater than when the day ends, that surely will not return anything

Change

PHP Code:

$this->db->where('start_time < ', $day_start);
$this->db->where('start_time > ', $day_end); 


To

PHP Code:

$this->db->where('start_time > ', $day_start);
$this->db->where('start_time < ', $day_end); 


Best wishes,

Paul
