Thanks for sharing the screenshot and your question!
What you're seeing is normal behavior in Linux. When you create folders using mkdir, Linux sets the timestamp (shown in ls -lrt) to the current date and time, not based on the folder name. This is because Linux filesystems like ext4 and xfs track creation time (btime) internally, but do not allow users to manually set or change it.
The only timestamps that can be changed from userspace are:
Modification time (mtime)
Access time (atime)
So, even if your folders are named like rundeck-01092025, rundeck-02092025, etc., the timestamps you see are simply the moment the folder was created, in your case, all showing September 1st.
If you want the visible timestamps to match the dates in the folder names (just for clarity or for alignment with future schedule logic), you can use the touch command to set the modification time manually.
Here’s how you can do it all in a single line:
sudo bash -c "for offset in {0..30}; do folder=\"rundeck-\$(date -d \"+\$offset day\" +%d%m%Y)\"; mkdir -p \"\$folder\"; chown rundeck:rundeck \"\$folder\"; touch -d \"+\$offset day\" \"\$folder\"; done"
This command:
Creates 31 folders with future-dated names
Assigns them to the rundeck user and group
Sets the folder’s mtime to match its name (e.g., rundeck-01092025 will show a timestamp of Sep 1, 2025)
Note: This changes only the mtime, not the true btime (creation time), which Linux does not allow you to modify.
You can use the stat command to view btime

@jeesshnasree for creating the folder with old timestamp :
#mkdir <dir>
#touch -d '30 days ago' <dir>
To remove folders which are older than a month and in the current path , use :
#find . -mindepth 1 -maxdepth 1 -type d -mtime +30 -exec rm -rf {} \;
refer man page touch : https://man7.org/linux/man-pages/man1/touch.1.html
