You can use -mtime of find(1). -mtime -1 would list files newer than 24 hours. Alternatively, you can make a timestamp every midnight (from cron), and check with -nt, if your shell's test implementation has it. See man test for details. E.g.:
Code:
find /path/to/dir -mtime -1 > newFiles.lst
...
if grep -q $file newFiles.lst ; then 
  echo "file $file is new"
else
  echo "old stuff"
fi

or
Code:
if [ $file -nt $timestamp ] ; then
  echo "$file is new"
fi
