Photos from two cameras out of sequence because of time difference

I was taking photos on a school trip recently and got back to discover the two cameras I was using had different times set. So when you put all the photos in a directory and sort in time order, they're out of sequence.

I found a quick and easy fix (assuming you're happy to fire up a command prompt) with Matthias Wandel's jhead EXIF jpeg header manipulation tool

simple case of running the command

• jhead -ta+00:10 IMG*.jpg

to add 10 minutes to all the Canon images

and then

• jhead -ta-00:06 P*.jpg

to take 6 minutes off the Lumix images

Job done, back in sequence - its a powerful tool.
Will certainly be back to use that one again.
