So long as xargs only invokes ls once.

I don't think there's any need for that while loop. You should be able to get it done using find's exec primary.
Code:
find "$basedir" -mtime 1 -exec stat -c '%Y %n' {} + | sort ....

Save yourself a few calls to stat as well.

Also, if you reverse the sort order, you can use head and finish faster (no need to pipe everything through cut and tail).
