Bash to select oldest folder in directory automatically and log process

The `bash` below uses the oldest folder in the specified directory and logs it. The goes though an analysis process and creates a log. My problem is that if there are 3 folders in the directory folder1,folder2,folder3, the bash is using folder2 for the analysis eventhough folder1 is the oldest folder in the directory. Is the find command missing something? Also, is there a better way to log the folder used? That portion is in bold. Thank you Smilie.

Bash
Code:
#!/bin/bash

dir=/home/cmccabe/Desktop/NGS/test
{
  read -r -d $'\t' time && read -r -d '' foldername
} < <(find "$dir" -maxdepth 1 -mindepth 1 -printf '%T+\t%P\0' | sort -z -r )
printf "The oldest folder is $foldername, created on $time" "and will be used for analysis on $(date "+%D %r")" >> /home/cmccabe/Desktop/NGS/test/log.txt

logfile=/home/cmccabe/Desktop/NGS/test/$foldername/process.log
for f in /home/cmccabe/Desktop/NGS/test/$foldername/bedtools/*.txt ; do
     echo "Start BedTools target base depth creation: $(date) - File: $f"
     bname=`basename $f`
     pref=${bname%%.txt}
     awk '{ sum += $7; n++ } END { if (n > 0) print sum / n; }' $f > /home/cmccabe/Desktop/NGS/test/$foldername/bedtools/${pref}_depth.bed
     echo "End BedTools target base depth creation: $(date) - File: $f"
done >> "$logfile"

edit: I must have had a typo as it seems fine now... thank you Smilie.

NAME
new - report on folders with new messages fnext - set current folder to next folder with new messages fprev - set current folder to previous folder with new messages unseen - scan new messages in all folders with new messages SYNOPSIS
new [sequences] [-mode mode] [-folders foldersfile] [-version] [-help] fnext is equivalent to new -mode fnext fprev is equivalent to new -mode fprev unseen is equivalent to new -mode unseen DESCRIPTION
New in its default mode produces a one-line-per-folder listing of all folders containing messages in the listed sequences or in the sequences listed in the profile entry "Unseen-Sequence". Each line contains the folder, the number of messages in the desired sequences, and the message lists from the .mh_sequences file. For example: foo 11.* 40-50 bar 380. 760-772 824-828 total 391. The `*' on foo indicates that it is the current folder. The last line shows the total number of messages in the desired sequences. New crawls the folder hierarchy recursively to find all folders, and prints them in lexicographic order. Override this behavior by provid- ing foldersfile containing the pre-sorted list of folders new should check, one per line. In fnext and fprev modes, new instead changes to the next or previous matching folder, respectively. In unseen mode, new executes scan sequences for each matching folder. FILES
