On Debian, and presumably Debian based system check

/var/log/installer

syslog

search rtc_cmos - setting system clock | clock-setup

or stat syslog

Xorg.0.log always notes the date when it starts a log - Log file: "/var/log/Xorg.0.log", Time:

Good article.

On my new Linux 19.1 OS:

Code:
~$ ls -lact --full-time /etc | tail -1 | awk '{print $6,$7}'

Anybody else like to give us your information when your Linux OS was installed?

I am not sure if I understand your question.

I bought a new tower that had Windows 10 installed when I bought it and I deleted the Windows 10 and installed Linux Mint 19.1, Cinnamon 64-bit, Tessa.

The kernel information of the installed Linux 19.1 OS is:

Quote:
~$ uname -r
4.15.0-55-generic
I got the code information that I listed in my post in the article that I reviewed, "How to Find Out Linux Operating system (OS) Installation And Time". If you read the article you can find the code.

I didn't understand "Linux Mint 19.1" is a Linux based OS, not actually Linux 19.1 OS.



Linux Mint is based on Ubuntu, Ubuntu is based on Debian, Debian is built on the Linux kernel.



Linux it's self, is not a stand alone OS. As I understand.

Now I fully understand your reasoning. Thank you.
