Validation rules for date and time in CodeIgniter

Question

I am using PHP CodeIgniter. I have kept validation in a function. I do not know the validation rule for date and time calendar in CodeIgniter. Can anyone give me an idea?

My code is :

$this->ref_valid_rules = array( 
                        array('field' => 'meeting_heading',
                              'label' => 'meeting heading',
                              'rules' => 'trim|required'), 
                        array('field' => 'meeting_agenda',
                              'label' => 'meeting agenda',
                              'rules' => 'trim|required'),
                        array('field' => 'venue',
                              'label' => 'venue',
                              'rules' => 'trim|required'),
                        array('field' => 'date',
                              'label' => 'date time',
                              'rules' => 'required') );

You can try

$this->form_validation->set_rules('date', 'date time', 'regex_match[(0[1-9]|1[0-9]|2[0-9]|3(0|1))-(0[1-9]|1[0-2])-\d{4}]');

or you can try the set validation rules using callbacks

  function regex_date($date) {

    $data =  preg_match('@^Jan|Feb|Mar|Apr|May|June|July|Aug|Sept|Oct|Nov|Dec-[0-9]{2}-[0-9]{4} [0-9]{2}:[0-9]{2}:[0-9]{2}$@', $date);

    return $data;
}

the function will return true or false
