    Field 
Detail


Name Key 
public string Name



  
General Information:
The Name property uniquely identifies the 
  Service and provides an indication of the functionality that is managed. This 
  functionality is described in more detail in the Description property of the 
  object.

Product Specific Usage:
In Intel AMT Release 6.0 and 
  later releases value is "Intel(r) AMT Time Synchronization 
  Service"

-------------

CreationClassName Key 
public string CreationClassName



  
General Information:
CreationClassName indicates the name of the 
  class or the subclass that is used in the creation of an instance. When used 
  with the other key properties of this class, this property allows all 
  instances of this class and its subclasses to be uniquely 
  identified.

Product Specific Usage:
In Intel AMT Release 6.0 
  and later releases value is 
  "AMT_TimeSynchronizationService"

SystemName Key 
public string SystemName

  System.

  later releases value is "Intel(r) 
  AMT"

SystemCreationClassName Key 
public string SystemCreationClassName



  
General Information:
The CreationClassName of the scoping 
  System.

Product Specific Usage:
In Intel AMT Release 6.0 and 
  later releases value is 
  "CIM_ComputerSystem"

Qualifiers:
-------------
Key
MaxLen=20
Propagated=CIM_System.CreationClassName


  

  





ElementName 
public string ElementName



  
General Information:
A user-friendly name for the object. This 
  property allows each instance to define a user-friendly name in addition to 
  its key properties, identity data, and description information. 
Note that 
  the Name property of ManagedSystemElement is also defined as a user-friendly 
  name. But, it is often subclassed to be a Key. It is not reasonable that the 
  same property can convey both identity and a user-friendly name, without 
  inconsistencies. Where Name exists and is not a Key (such as for instances of 
  LogicalDevice), the same information can be present in both the Name and 
  ElementName properties. Note that if there is an associated instance of 
  CIM_EnabledLogicalElementCapabilities, restrictions on this properties may 
  exist as defined in ElementNameMask and MaxElementNameLen properties defined 
  in that class.

Product Specific Usage:
In Intel AMT Release 
  6.0 and later releases value is "Intel(r) AMT Time Synchronization 
  Service"

-------------
MaxLen=45


  

  





EnabledState 
public uint16 EnabledState



  
General Information:
EnabledState is an integer enumeration that 
  indicates the enabled and disabled states of an element. It can also indicate 
  the transitions between these requested states. For example, shutting down 
  (value=4) and starting (value=10) are transient states between enabled and 
  disabled. The following text briefly summarizes the various enabled and 
  disabled states: 
Enabled (2) indicates that the element is or could be 
  executing commands, will process any queued commands, and queues new requests. 
  
Disabled (3) indicates that the element will not execute commands and will 
  drop any new requests. 
Shutting Down (4) indicates that the element is in 
  the process of going to a Disabled state. 
Not Applicable (5) indicates the 
  element does not support being enabled or disabled. 
Enabled but Offline 
  (6) indicates that the element might be completing commands, and will drop any 
  new requests. 
Test (7) indicates that the element is in a test state. 
  
Deferred (8) indicates that the element might be completing commands, but 
  will queue any new requests. 
Quiesce (9) indicates that the element is 
  enabled but in a restricted mode.
Starting (10) indicates that the element 
  is in the process of going to an Enabled state. New requests are 
  queued.

RequestedState 
public uint16 RequestedState



  
General Information:
RequestedState is an integer enumeration 
  that indicates the last requested or desired state for the element, 
  irrespective of the mechanism through which it was requested. The actual state 
  of the element is represented by EnabledState. This property is provided to 
  compare the last requested and current enabled or disabled states. Note that 
  when EnabledState is set to 5 ("Not Applicable"), then this property has no 
  meaning. Refer to the EnabledState property description for explanations of 
  the values in the RequestedState enumeration. 
"Unknown" (0) indicates the 
  last requested state for the element is unknown.
Note that the value "No 
  Change" (5) has been deprecated in lieu of indicating the last requested state 
  is "Unknown" (0). If the last requested or desired state is unknown, 
  RequestedState should have the value "Unknown" (0), but may have the value "No 
  Change" (5).Offline (6) indicates that the element has been requested to 
  transition to the Enabled but Offline EnabledState. 
It should be noted 
  that there are two new values in RequestedState that build on the statuses of 
  EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing 
  a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the 
  element is first "Disabled" and then "Enabled". The distinction between 
  requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests 
  an orderly transition to the Disabled state, and might involve removing power, 
  to completely erase any existing state. The Disabled state requests an 
  immediate disabling of the element, such that it will not execute or accept 
  any commands or processing requests. 

This property is set as the 
  result of a method invocation (such as Start or StopService on CIM_Service), 
  or can be overridden and defined as WRITEable in a subclass. The method 
  approach is considered superior to a WRITEable property, because it allows an 
  explicit invocation of the operation and the return of a result code. 
  

If knowledge of the last RequestedState is not supported for the 
  EnabledLogicalElement, the property shall be NULL or have the value 12 "Not 
  Applicable".

LocalTimeSyncEnabled 
public uint32 LocalTimeSyncEnabled



  
General Information:
Determines if user with LOCAL_SYSTEM_REALM 
  permission can set the time.The values are: DEFAULT_TRUE - Time sync is 
  enabled by default. Was not configured to enabled or disabled by the 
  configuration SW.CONFIGURED_TRUE - Time Sync is enabled and configured by 
  configuration SW to TRUE. This option is required in order to differentiate 
  between legacy configuration SW that do not support this setting and new SW 
  that can configure it to TRUE.FALSE - Time Sync is

Ta0 
    
General Information:
An unsigned 32-bit value representing the 
    local time as the number of seconds from 00:00:00, January 1, 1970 UTC. This 
    format is sufficient to maintain time stamps with one-second resolution past 
    the year 2100. This is based on a longstanding UNIX-based standard for 
    timekeeping, which represents time as the number of seconds from 00:00:00, 
    January 1, 1970 UTC. Similar time formats are used in ANSI 
    C.
