Odd File Timestamp for /config/big3d/client.crt

That is epoch time:

https://en.wikipedia.org/wiki/Unix_time

I just check that I have the same in my lab unit. If you want to change, just do:

touch /config/big3d/client.crt

[root@LABBIGIQ:Active] big3d  ll
total 8
-rw------- 1 root root 1468 Jan  1  1970 client.crt
[root@LABBIGIQ:Active] big3d  touch client.crt
[root@LABBIGIQ:Active] big3d  ll
total 8
-rw------- 1 root root 1468 Oct 21 14:07 client.crt
[root@LABBIGIQ:Active] big3d 

That is just the file timestamp, nothing related with the certificate dates.

Run this command to get the certificate information:

openssl x509 -noout -text -in /config/big3d/client.crt
