`rpm -qi basesystem` shows the update date not installed date

[tazihad]

rpm -qi basesystem shows the update date to new image. But it should show the first time installed date of the system.

Here the Install Date should be the date I have installed the system. Instead it shows the last update date. And now there's no way to know the exact date I have installed Atomic system.

By design, rpm-ostree builds each version from scratch. This means that RPMs are always freshly installed for each update and rpm will thus only show you the date the update has been composed (created).

You should use something else to find out when your system was installed. Maybe look at the Anaconda log in /root/?
