This worked for me in fish shell. Copy the files, then execute this to 
do some translations on the “content created” field and save it back 
to the “date created” field.

```
for file in *.eml
     set created (mdls -name kMDItemContentCreationDate -raw "$file" )
     set translated (date -jf "%Y-%m-%d %H:%M:%S %z" "$created" 
"+%Y-%m-%d %I:%M:%S %p" | sed 
's/\([0-9]\{4\}\)-\([0-9]\{2\}\)-\([0-9]\{2\}\) 
\([0-9]\{2\}\):\([0-9]\{2\}\):\([0-9]\{2\}\).*$/\2\/\3\/\1 \4:\5:\6/')
     SetFile -d "$translated" "$file"
end
```
