check_files.pl issue with directory listings (remote file system)

[nebj00la]

I've mounted a cifs share, and sometimes the times do not show up in the output of "ls -l" or "ls -la", etc. I've found the times always show up with the following usage:

ls -l --time-style=+"%M %D:%H:%M"
ls --full-time

There are other methods that show the time, as well. The main problem is that I can't find a way for the script to measure "file ages" properly due to the issue in the mounted directory.

Examples:

[root@sa-atms-sr1-sysmon cctv_images]# ls -l

-rwxrwSrwx 1 root root 79953 Jan 10 02:07 foo.jpg

-rwxrwSrwx 1 root root 50507 Jan 10 2014 [GP][CCTV 102].jpg

[root@sa-atms-sr1-sysmon cctv_images]# ls --full-time
