That works great.. I would probably use a calculated property so it returns
an object instead of string
Get-WMIObject -Class "MicrosoftDNS_AType" -Namespace
"root\MicrosoftDNS" -Comp $DNSServer -Filter "DomainName='$Domain'" |
Select-Object
OwnerName,@{n="TimeStamp";e={(Get-Date("01/01/1601")).AddHours($_.TimeStamp)}}
This way you could | to a filter like
... | ?{$_.TimeStamp -gt $date}
or
... | ?{$_.OwnerName -match }

Good of you to offer  I think I have it though, well one of many possible,
any improvements recommended?
$DNSServer = ""
$Domain = ""
Get-WMIObject -Class "MicrosoftDNS_AType" -Namespace "root\MicrosoftDNS" `
-ComputerName $DNSServer -Filter "DomainName='$Domain'" `
| ForEach { ($_.OwnerName) + " " + `
(Get-Date("01/01/1601")).AddHours($_.TimeStamp) }
Might be easier to read spread out though.

I will rewrite them in Powershell if you like. If you want it as a
learning exercise, I am here to help with that as well.
