how to check the ESXi Install date

is there a powerCli script that can produce the ESXi install date ( not the patch date ) for the physical hosts ?
I am trying to see what new ESXi server we deployed in 2015.
Any help would be appreciated.

have you hosts been patched (ever!) or just standard ESXi install ?

no patches.
Just Esxi Install.

okay, check for the date of esx-base, this can give an indication of the install date.

also a

 esxcli software profile get

can give you a creation time.

try this

 esxcli software vib list | awk {'print $5'} | sort | uniq | sort -rn

Open in new window

using the above code, gives dates of all changes and patches, and if you look at the first date, this gives a good date for installation date.
