  This is getting "curiouser and curiouser".  I should have done this
sooner.  I assumed that the datestamp and EXIF data would be the same.
But checking "properties" with gqview shows the EXIF date data is
correct, with the file datestamp being out to lunch...

[i660][waltdnes][~/camera/20180824] exiftool -T -CreateDate IMG_0363.jpg 
2018:08:24 14:12:19

[i660][waltdnes][~/camera/20180824] ll -og IMG_0363.jpg 
-rw-r--r-- 1 477731 Jan 26  2013 IMG_0363.jpg

  Given this info, I can cobble together a short script.  A "for" loop
cycles through "*.jpg".  Read "CreateDate" from the EXIF data, and feed
it into the "touch" command, which would reset the physical file
datestamp.
