date REAL about when is INSTALLED (not compiled, not delivery) CentOS

[Windows]

we are in VPS + CentOS 7.9

we REINSTALL OS CentOs yesterday

when we run:

Code: Select all

ls -lctd --time-style=+"%d-%m-%Y %H:%M:%S" /etc | tail -1 | awk '{print $6, $7, $8}'

this show current time minus 2 hours.

when we run

Code: Select all

stat / | awk '/Birth: /{print $1,$2}'

this show Birth: -

. . .

we try others commands but ever result is empty or "Birth: -" or "creazy date". . .

never we obtain REAL DATE.

please remember:
we REINSTALL OS CentOs yesterday


some command for obtain REAL timestamp or date of CentOs VIRTUAL installation ?


thanks

Look at the timestamp on /etc/hostname ?

rpm -qi basesystem | grep Install
?

Maybe this: rpm -qa --last
