The version of vSphere running on VMware Cloud on AWS introduces a new createData property under VM->config->createDate[1] which provides the date/time of when a VM is created. Today this is currently not available outside of VMWonAWS, but if/when this field might be available, it would be nice to have it included as a default property with the Get-VM cmdlet
