hello everybody...
i have the following question:
i used geosetter to geotag my pictures. their exif data now includes gps-coordinates as well as the tags "gpsdatestamp" and "gpstimestamp". since these two tags contain the correct date/time information, i would like to use them to overwrite the other date/time tags (e.g. "datetimeoriginal"). however, i couldn't figure out how to do this.
i read the faq and searched the forum but i only found answers for performing the opposite task: setting "gpsdatestamp" and "gpstimestamp" to the values from "datetimeoriginal. this is done by
C:\exiftool-8.42>exiftool.exe "-gpsdatestamp<datetimeoriginal" image.jpg
or
C:\exiftool-8.42>exiftool.exe "-gpstimestamp<datetimeoriginal" image.jpg
and works fine.
if i try to do it just the other way round, i.e.
C:\exiftool-8.42>exiftool.exe "-datetimeoriginal<gpsdatestamp" image.jpg
i get the output
Warning: [minor] Unrecognized MakerNotes - image.jpg
1 image files updated
but although exiftool claims to have updated the file, it didn't change anything!
trying it with "gpstimestamp" instead of "gpsdatestamp", i.e.
C:\exiftool-8.42>exiftool.exe "-datetimeoriginal<gpstimestamp" image.jpg
at least results in a correct warning message
Warning: [minor] Unrecognized MakerNotes - image.jpg
Warning: No writable tags found - image.jpg
0 image files updated
1 image files unchanged
but also does not change anything!
is there a solution to my problem?
thanks.

Try "-datetimeoriginal<gpsdatetime".
This uses the Composite:GPSDateTime tag which is derived from GPS:GPSDateStamp and GPS:GPSTimeStamp.
