time mismatch after convert with format_date

Question

In my custom module, I converted time from database like ('17:00:00') with format_date(). After I converted this I got a wrong time (17:10). Please check my code, I am also naive drupal develper.

$form['departure_time'] = array(
  '#type' => 'textfield',
  '#maxlength' => 10, 
  '#title' => t('Departure Time'),  
  '#default_value' => format_date(strtotime($data -> departure_time),'custom', 'H:m'),
  '#description' => t("You Need To Add Departure Time.<< 00:00"),
  '#required' => TRUE,
);

Answer 1

As listed in the documentation http://php.net/manual/en/function.date.php lowercase m is for month. For minutes you should use i.

$dep= format_date(strtotime($data -> departure_time),'custom', 'H:i'); 

Answer 2

Just of note, you don't need to pass the date through t() as format_date() handles this itself through _format_date_callback() for reference. You just have to pass in the langcode yourself.
