File Test -A problem on SunOS 5.9 & perl 5.8.3

zakzebrowski has asked for the wisdom of the Perl Monks concerning the following question:

All,

I've run into a strange file test problem. When I do a -A on a file, the return value is 0.0000 for the age of the file. That would be fine if the file was open and in use, but it's not in use, according to the command lsof. The uname -r -s returns SunOS 5.9 and Perl -V returns 5.8.3. The code worked fine on SunOS 5.8 under perl 5.6.1. Any ideas? BTW, -C and -M return resonable values... (Google and perlmonks (as far as I searched) returned no meaningfull results.)

UPDATE: It appears to be localized to the operating system, and is not a perl bug, special thanks to dave_the_m for localizing the problem!
Cheers,

    add a system("ls -u /the/file") to your code directly after the -A and see what the OS thinks the last accessed time was.

      This doesn't work. Ideas? Output:
      bash-2.05$ls -u /tmp/file.dat
file.dat
bash-2.05$ls -u /tmp/somedir
bash-2.05$

        Sorry, that should be ls -lu
