Help changing date and times on a vast scale

[DanielMislati]

I need help, for ages now my date and time settings have been a year off and now when I look back they are all in the wrong times, I use a Nikon D3300 and I have narrowed it down to a formula which can tell me the correct date and time but I'm just wondering if there is a way I can just change them all by adding a formula, say +8 to every day on each picture so if the date was 07/07/2016 it will now be 15/07/2016 and that change would occur for every picture. Otherwise I will have to change them manually but that would mean changing the dates and times of 800+ photos and videos. Any reply is helpful and thank you in Advance.

If I was close to to you, and if you provided the food and drink, we could each take half of the project and get it done in half the time.

What image organizer/viewer/manager do you use? That is where you should be looking.

Sounds like a plan

Thanks, this should work, I'll try when I get home, currently I don't use anything to organize pictures but I will try one of these, the picasa (whatever) one seems to be able to update all photos with the same incrimental adjustment.

That's something you might want to look into. These kinds of programs make it a lot easier to view and find things. I use ACDSee (even though I have Lightroom). It also lets me easily adjust date/time by an increment--but its not free.

I used to adjust times frequently to get images in the right order when I'd used multiple cameras on a trip. I'd use each to take a reference photo of the time displayed all on the same device then then calculate an offset. Now I use a custom import program (wrote it myself). It adjusts date/time during import using clock drift profiles for each camera. My camera clocks drift by between 1/2 sec and 2 seconds per day. Each camera's drift is extremely predictable. Now I never adjust camera clocks and just let the software fix things. Its stupid that all photo import tools don't have clock drift profiling and correction.
