indeed, I rename all my files after import:
  exiv2 mv \-k \-r %y%m%d_%H%M%S_:basename: \.\/*.{nef,jpg}'


but, this uses the exif date within the file.  if the camera date-time was
incorrect, so would be my file names.  so before a shoot, I synchronize
the date-time on all of my bodies, then go shoot.

if I found that I incorrectly set the date-time, I would run another
script to offset the file name to the correct value.

but I do not change anything within the original file.  it's name will
provide the correct date-time.  and I can correct dt's database to show
the same using sqlitebrowser or ...
