Hello,

 

Merry Eastern to everyone.

 

I am just trying to understand where and how DT retrieves data from the exifs.

After reading the thread, I did a exiv2 -v ad -a -1:00:00 Test.nef.

The photo named Test.nef is one with no importance, so no matter what could 
happen to it.

Before applying the command to it, DT displayed 18:35:15 as shooting time.

After that, although exiv2 told it had modified 3 instances of the time, DT 
still displayed 18:35:15 instead of 17:35:15.

As I re-imported it after removing it frome the database, it can not be a 
matter of persistent data.

So, again, where does DT retrieve this unmodified time ?
