[Output only] The time at which Cloud IoT Core received the
acknowledgment from the device, indicating that the device has received
this configuration version. If this field is not present, the device has
not yet acknowledged that it received this version. Note that when
the config was sent to the device, many config versions may have been
available in Cloud IoT Core while the device was disconnected, and on
connection, only the latest version is sent to the device. Some
versions may never be sent to the device, and therefore are never
acknowledged. This timestamp is set by Cloud IoT Core.
[Output only] The version of this update. The version number is assigned by
the server, and is always greater than 0 after device creation. The
version must be 0 on the CreateDevice request if a config is
specified; the response of CreateDevice will always have a value of 1.
