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.
