Hi Marco

Thanks for the info!

OK, now the interesting thing is that this updates the time, but not the
date! So, I get the correct (modulo the buglet I'l describe later)
timestamp, but not date if I do this.

OK, this gets updates the time, and date stamp, and read the orientation
from the file.  Unfortunately, for the cameras that don't have an
orientation sensor, they just stubbornly record the wrong orientation,
and since I have, at the moment, more photos from this kind of camera,
it'll be better for me to only update the timestamps.

So, I tried guessing and changing

(*it)->readExif((*it)->fileName(),ImageInfo::Time);
to
(*it)->readExif((*it)->fileName(),ImageInfo::Date);
but this did not seem to work.  How can I get it to update both the time
and date?

OK, and now onto the buglet. It seems that the 10s of seconds are
incorrectly imported.  The 10's of seconds are always 0.

That is, times are always xx:xx:0x, where the x's represent the correct
time info. This seems to be consistent among all my photos.

Thanks for your time
