in thread comparing 2 file time date stamps


Below are the results. Everything looks right. I am confused.

I want to mention that I saw the following. I have a file with a dt stamp of 11/4 in dir 1. I make a copy of it expecting the same date. It changed the date to the same date of a file with the same name in directory 2. O no.

initial dt stamp

c:/usr/www/steepusa/stage/KY/KY3.gif: 1414863057

1 As string: Sat Nov  1 13:30:57 2014
2 As string: Sat Nov  1 13:30:57 2014

after 1st open and close

1 As string: Thu Nov  6 10:21:29 2014
2 As string: Thu Nov  6 10:21:29 2014

30 sec wait - file 2 opened and closed again

file 1 and 2 after file 2 open/close

    Ok, so stat is working as expected. In that case most likely the files do have the same modification date and for some reason your impression that the dates are different is incorrect.

    Perl is the programming world's equivalent of English
      GrandFather, the list of files presented to me by Windows 7 when I go into the stage directory is what I'm basing my impression on. The list shows that the date of files in the stage directory is not what stat is returning to me in my program and not the same as the like-named file in the KY directory.

      And I do reproduce this result for 12 file pairs of like-named files in these 2 directories in my application. It looks right in the code you suggested I do, but not in my application or the code Corion suggested I do or the javascript I did. I am confused. I not sure how to proceed.

      The dates of these 12 file pairs that I've chosen for diagnostic purposes are not the same as shown by the windows file list, but all the diags I've done (my app, what you and corion suggested, and the javasscript) show that the dates of the pairs are the same, the 2nd file (stage) having the date of the 1st (KY), or the 2nd file (stage directory) stamp is different but incorrect.
