# How to use it
# Place it in the folder where you have the photos/other files
# chmod +x efif-add-missing-ts.sh
# ./efif-add-missing-ts.sh . "2017:09:22 22:25:00"
# It creates copies of the original files (they can be removed with rm -rf *_original )

# NOTICE:
# The first argument should signify the location of the files but the script needs to be still in the same folder as the files are.
