With the following command I have been able to list all the directories relative to the current directory along with the epoch time last modified:

find . -exec stat -c '%n: %Y' {} \;

the output looks something like this:

.: 1569247414
./a_file.txt: 1561624333
./some_folder: 1561624645
./some_folder/some_file.txt: 1561624645
./some_folder/another_file.txt: 1536557809

How would I go about getting rid of the "./" appearing at the beginning of every entry, and add a '/' if it is a directory?

As a bonus, getting rid of the first entry '.' which is just the current folder would be nice.

Cheers

Question..
Is possible to dig "real" access time of file copied from remote server and using it by including from another script?

What I need.
I need to know which files on server are unused/untouched for long time, but I have only ftp access, so I must download files. Curlftps not solve this.
And what about files only included from another file, for example include in php script? Does included file change his access time when is accessed by include from another script?
Edited. Tested included file access time change, it change access time when file is "touched" by include script.

Tested
When I copied the file, there was quite strange access time, file should be accessed very often.

Thank you.

Edited.
Just info, that when I connect via sshfs or curlftps, seems that display right access date, but time is only at 0, which is ok for me. Is this date real or am I wrong? And is Access time "real"? Thanks.

When you use sadf to make a report from sysstat's datafile, the following lines will be shown:

ncm     3       2015-05-11 03:57:15 UTC all     %%user  0.08
ncm     3       2015-05-11 03:57:15 UTC all     %%nice  0.00
ncm     3       2015-05-11 03:57:15 UTC all     %%system        0.08
ncm     3       2015-05-11 03:57:15 UTC all     %%iowait        0.00
ncm     3       2015-05-11 03:57:15 UTC all     %%steal 0.00
ncm     3       2015-05-11 03:57:15 UTC all     %%idle  99.84

What does the second filed of this output mean?

What is the difference between Modify and Change in stat output? When I run this command:

stat myfile

I am getting two lines with identical timestamps:

Modify: 2015-03-24 12:34:56.12345678
Change: 2015-03-24 12:34:56.12345678

What is the deal?
