 When an image has the EXIF field DateTimeDigitized defined, but set to an
 empty timestamp, like
 {{{
     :  :     :  :
 }}}
 a PHP notice is thrown during upload.

 I don't know how common this is, but I've seen it on several family photos
 that were scanned by my aunt. The EXIF info mentions both HP Scanjet 4370,
 FinePixViewer Ver.4.2, and FUJIFILM.

 Anyway, it can be pre-empted with this between the two calls to explode():

 {{{
 if ( ':' === $date ) {
     return '';
 }
 }}}

 I've attached a sample file to replicate the problem.
