distance_of_time_in_words gone crazy!

Question

distance_of_time_in_words(strtotime(2010-08-07), strtotime(2010-08-01))

returns '6 minutes'

$a = '2010-08-02 00:39:29'
$b = '2010-08-01'
distance_of_time_in_words($a, $b)

returns 'less than a minute'

$a = '2010-08-02 00:39:29'
$b = '2010-08-01 20:08:00'
distance_of_time_in_words($a, $b)

returns 'less than a minute'

I wonder if I'm going wrong in the conversion.. Does it accept a timestamp or date? Thanks

Answer 1

Checking it's source code it seems it needs timestamps (it does some calculations at the beginning of the function).

Answer 2

// call
distance_of_time_in_words(getUnixTimestamp(), getUnixTimestamp($bill->created_at));

// utility method
public function getUnixTimestamp($datetime = null)
{
  return date("U", (($datetime) ? strtotime($datetime) : time()));
}

Hope this will help others!
