CurrentTimeZonesint16
DescriptionstringCurrentTimeZone indicates the number of minutes the OperatingSystem is offset from Greenwich Mean Time. Either the number is positive, negative or zero.
PUnitstringminute

Distributedboolean
DescriptionstringBoolean indicating whether the OperatingSystem is distributed across several ComputerSystem nodes. If so, these nodes should be grouped as a Cluster.
Familystring
DescriptionstringIdentifies the family that the OperatingSystem belongs to as a structured string. A family refers to a set of OperatingSystems that are similar but not identical from a hardware or software point of view (for example, Windows or Linux family of operating systems). The format for the family string values shall conform to the 'family' ABNF rule: family = org-id ":" family-id org-id = INDENTIFIER family-id = INST-INDENTIFIER Org-id shall include a copyright, trademarked, or otherwise unique name that is owned by the business entity that produces the OperatingSystem or that is a registered ID assigned to that business entity by a recognized global authority. In addition, to ensure uniqueness, org-id and family-id shall not contain a colon (:). Family string values defined by the DMTF shall have an org-id of 'DMTF'.
