Nice script!

FWIW: the $filename of the git log command needs to be quoted with double quotes, otherwise the command will fail for files with spaces in the pathname and you will get only the filename without the timestamp:

git ls-tree -r --name-only HEAD | while read filename; do   
   echo "$(git log -1 --date=iso --format="%ad |" -- "$filename") $filename" 
done

See the following example:

~/example$ tree
.
└── foo bar baz.txt

0 directories, 1 file

without quotes

~/example$ git ls-tree -r --name-only HEAD | while read filename; do echo "$(git log -1 --date=iso --format="%ad |" -- $filename) $filename" ; done
 foo bar baz.txt

with quotes

~/example$ git ls-tree -r --name-only HEAD | while read filename; do echo "$(git log -1 --date=iso --format="%ad |" -- "$filename") $filename" ; done
2022-11-11 16:39:49 +0100 | foo bar baz.txt

Unfortunately, it also fails with non-ascii characters in the filename:

~/example$ tree
.
├── ä_ö_ü.txt
└── foo bar baz.txt

0 directories, 2 files
~/example$ git ls-tree -r HEAD
100644 blob 924665ce4c939bd9fdbfec512cdf379f0c8696c4	foo bar baz.txt
100644 blob 6718a7cf7fb4f41ea7ed4aefad5dd1946a9bb2b4	"\303\244_\303\266_\303\274.txt"

If you want to handle cases where a file has been renamed but not otherwise modified since (and in those cases see the time stamp before the rename), add:

--follow --diff-filter=r

This looks for renames (--follow), then filters them out (lower-case r).
