Date index for Sep 2003

Hello,

I'm pretty sure that this time is indeed a bug ;)

If you will try to call atkTimeAttribute->display() with something like 
array('hours'=>00, 'minutes'=>[XX]), you will notice that it returns an 
empty string instead of '00:XX'. Basically any time between 00:00 and 
00:59 will not be displayed.

In the display() method you have:

  if (empty($value["hours"])) return "";

I guess this should be replaced with something like:

  if (empty($value["hours"]) and $value["hours"]!="00")
	return "";


This bug also affects atkDateTimeAttribute->display(), which relies on 
atkTimeAttribute->display().


Best regards,
Sebastian
