Add exif creation time with correct timezone (TZD) to filename
To change UTC time to reflect your timezone, run the output of mdls thru the date command. You can also format the output of the date command.
utcfiledate=$( mdls -n kMDItemContentCreationDate -raw  FILE)

date -f '%F %T %z' -j &quot;$utcfiledate&quot; '+%F %T'

To remove the colons from the output
date -f '%F %T %z' -j &quot;$utcfiledate&quot; '+%F %H%M%S'
