Yes, I did; so thank you
But I can only assume, that this is the answer to the problem- and that this will not happen again. If it will and I somehow take notice of it, I will get back to report this
But on the side note:
I had to use lower case
%_file_mod_datetime_raw%
becuase with capitals
%_FILE_MOD_DATETIME_RAW%
the Column did not work- I clicked it and nothing ever happened. So it seems that this is another manifestation of this already semi-fixed bug:
In the Column management window you can use both both "%_filename" and "%_FILENAME%" for "Value" and "Sort By", but if you use "%_FILENAME%" for "Field" then it gets blocked- you can no longer change the name of the file in the main window. But you can change the TITLE and then copy it to the _FILENAME with action. So at the same time it is blocked and it is not And also it does not matter if you put "%_FILENAME_EXT%" or "%_filename_ext%"- they both work the same 100%. So you can have a setting…

So it is not a bug, just an example in difference between Unix Time and... time? [And that Unix Time thing is also why I keep stumbling upon that 1970 date when tempering with files creation date]
But if it not a bug, then why two files created with the same software [converter] within a span of less than an hour cannot be displayed in the correct order [with the %_file_mod_datetime% version]? It is not like between them "happened" thousands of leap seconds that coud somehow affect the saved time, right?
