SUMMARY
When selecting columns to display, both "Changed" and "Modified" are offered, which seems redundant, and "Created" is not offered.

STEPS TO REPRODUCE
1. right-click on any column title
2. the options of which columns to display are listed

OBSERVED RESULT
The columns available include both "Changed" and "Modified", which seems redundant, and the "Created" column is not offered at all. 

EXPECTED RESULT
The columns available should include one of "Changed" and "Modified", not both, and the "Created" column should be offered.

There are three file date-times displayed in Krusader. The mapping to POSIX-standard is
- "Modified" -> mtime
- "Changed" -> ctime
- "Accessed" -> atime

mtime and ctime are not the same. 

There is no standard way to get the "creation time" in Linux, not all filesystems support it.

Hello Alex, thank you for your reply.
Can you tell me how Modified and Changed times differ? I thought ctime 
was Created Time in Ext4.

Hi Alex, never mind my previous email. I just checked on Google (duh) 
and found out that mtime refers to the last modification time for the 
file, and ctime refers to the last modification time for the metadata.

I do have a request, though. In the menu, could "Changed Time" be 
renamed to "Metadata Changed Time"? It would clarify.

+1 for an additional support file-item / column with creation date.
- support for Linux file system
- support for NTFS

Otherwise a splendid file-manager.

KDE Dolphin has this possibility with correct creation date in both ext4 and NTFS as a column in the panel.
