You can check it easily by simple type 'date' in the terminal (mine showed an old date) You should update it from the terminal like that: date 1002173315.

One other thing to note is that as these installers are all designed "to update" then I'd be pretty sure they will run as an app if mounted to a Mac already running any OS older than the installer.

The El Capitan installer was specifically 'sold' that way. I haven't tried any of these older installers in a while, but in the past some were only valid if your computer could not run any newer OS. One thing to note is that the 'date/certificate issue' should now be fixed for all older installers & so shouldn't need any workaround in that respect.
