tks, but I have little reason for date/time changes.
I set date/time on all three bodies before leaving for a shoot
After transfer from cards to local storage, I run:
lc;exiv2 -T ./*.{nef,jpg}
lc lowercases file name
exiv2 *** changes file date/time from import date/time to shooting
date/time
exiv2 \-k \-r %y%m%d_%H%M%S_:basename: \.\/*.{nef,jpg}'
exiv2 *** changes the filename to
date/time+original filename
Then I import into dt.
