There are a lot different date from Tracker. Like :
 * filesystem creation date
 * filesystem last modification date
 * tracker database insertion date
 * dates from metadata (either ID3 tag, EXIF data or more recently the
date from filename demangling)

By creation date, I would like to match data from the file's description
(EXIF/ID3/filename demang/etc...), whereas the date is more related to
the day you got the file (filesystem).
