yo Ancient, thanks for your efforts. those files are all found in UDC and are already quite accurately sorted. especially when a file has date of creation information within its header or at least in its filename, then the original timestamp is not that important.
the very old tosec dats are already put together inside ..RomRoot\DATs Collection\DATs 1\TOSEC\TOSEC (Old)\2000-2004
even though these dont have date information, they at least have a version number attached. so they are already sorted.
