For this one, you probably want to replace \; with + to get the efficiency
boost, which would be pretty significant here. You probably wrote this
one a long time ago.

This one has a few minor bugs. It will fail on filenames that contain
newlines, or backslashes, or trailing whitespace, or leading whitespace.
It can be corrected, although sadly the corrected version is a bit uglier.
find . -type f -print0 | while IFS= read -rd '' file; do bash-function "$file";
done

This one looks like a variant of my "rlart" function:
rlart() {
find "${1:-.}" -type f -printf '%T@,%TY-%Tm-%Td,%TT,%p\0' |
sort -zn |
while IFS=, read -rd '' _ day time path; do
printf '%s %s %s\n' "$day" "${time%.*}" "$path"
done
}
I give a detailed explanation of an earlier iteration of that one on
<https://mywiki.wooledge.org/BashProgramming/03> for those who are
interested in that sort of thing. The explicit comma delimiters were
added more recently, to avoid losing trailing whitespace.
