Wrong Timestamp

[DueyDooDah]

Well, I am back from Greece and have a lot of work ahead to process the images my wife and I took. One of the first things I may need to do is change the timestamps in the metadata. Unfortunately, I forgot to change the timezone setting on the cameras so everything is 10 hours off.

Does anyone know of a utility that can adjust the image "time taken" data? It should do batches and adjust the date as needed. It also must be non-destructive and handle both RAW and JPEG.

Yes I do!

It's a command-line utility called ExifTool. Here is a link to the part of the page that describes changing the timestamp.

I use ExifTool and a batch file to add focal length data and comments to my photos taken with older lenses that don't provide focal length to the camera. I did a ton of searching before finding this very, very handy tool. It's not the most user-friendly, but it's very powerful.
