Get current time for all VM of the host or the cluster without authentication

[NiceAdmin]

Hello,

i want with powerCLi , obtain by host or by cluster the date-time and the VM name associate for each VM without authentication because each VM has its own password 

invoke-VMscript command given date-time but  we have to go through an identification, and the output don't give the name of the VM

It is possible

Thank you for your help

Without authentication this will be difficult, if not impossible, through Invoke-VMScript.
If your VMs are running Windows and are part of a domain and they have the VMware Tools installed, you could use the Get-WmiObject cmdlet.

Get-VM |

Select Name,@{N='DateTime';E={

    $obj = Get-WmiObject -ComputerName $_.Guest.HostName -Class Win32_operatingsystem

    $obj.ConvertToDateTime($obj.LocalDateTime)}}

For VMs that have another guest OS, or are missing any of the requirements above, it will be difficult to get their local date and time

thank you for your answer, it confirms what I understood, like it's not easy with the only command that can do it, except put the same password to all VM linux and VM windows server

Not necessarily.
I store multiple user/password combinations in the CredentialStore, then I try them one-by-one.

Note that I use the Host part of the credentialstoreitem as a lable, i.e. win1,win2,lin1...

$foundCreds = $false

foreach($cred in Get-VICredentialStoreItem){

    if(-not $foundCreds){

        Try{

            $result = Invoke-VMScript -VM $vm -ScriptText $winCode -ScriptType Bat -GuestUser $cred.User -GuestPassword $cred.Password -ErrorAction Stop

            $foundCreds = $true

            $correctCreds = $cred

        }

        Catch [VMware.VimAutomation.ViCore.Types.V1.ErrorHandling.InvalidGuestLogin] {

            $obj.GuestCreds = 'nok'

            $obj.InvokeScript = 'ok'

        }

        Catch{

            $obj.InvokeScript = 'nok'

        }

    }

}
