Here is yet another problem we didn't used to have.
I shoot with two 5D camera bodies. It saves on the dust issues, in that I don't have to change lenses as much, and I can cover a range from 24 to 200mm at a moment's notice. Last night I changed the datestamp on my cameras, as I had changed time zones. It was late, I was tired. I was an hour off between cameras today.
To complicate matters, the file numbers on one camera caught up with the other, so I couldn't just do a file number sort and rearrange in big batches. I had to grab groups of like and drag them bit by bit until there was some semblance of order in the day's take. Twelve hundred exposures had to be sorted manually.
Just like the old days.
When I need to adjust timestamps I use jhead or BreezeBrowser to first adjust the EXIF timestamp, then set the file's time to match the EXIF time. Both tools operate on single files or selected colletions of files.

I used to have problems when the file names from my two cameras collided. I fixed it by writing a simple script that renames all of my files according to exact time taken according to the EXIF data. For example, 2007-03-29-060205.jpg. Since I can't take more than one picture at a time, it almost guarantees they won't conflict.

I don't know about Canon, but my D200 allows me to put text into the metadata of each image. In my case, I put a copyright notice but I could easily add a camera ID. If you can do this with your Canons you would have a way of pairing a particular image with a particular camera...

In rereading my note I realize that I wasn't clear... The user defined text is attached to every image along with other metadata. Once defined it's automatic.

In re-rereading the original post I realize that I've provided a solution for a nonexistent problem. Never mind...:-)
