The best way i do not know:

Some ways:
Get the date from the creation time of the bosinstlog file
$ ls -l /var/adm/ras/bosinstlog

Get the earliest installed software on the system
$ lslpp -ch | cut -f7 -d: | grep "/" | awk '{ print $3 $1 $2 }' FS="/"
| sort -nu | head -1

where the second one is harder to fake

It works by me.
I made a small modification -- I list only "bos.rte.*" family ( lslpp
-ch "bos.rte.*" .... ).

Thanks Hajo.

Just keep in mind it's using the System Clock / Timezone during
install.

Not a big deal if it's off by +/- 12 hours, but when we had a drive and
planar board replaced the CE didn't set the time before installing.
The year was at 1970 which wasn't very funny at the time.
