Job [out]

A reference to the job. This parameter can be Null if the task is completed.

TimeoutPeriod [in]

The maximum amount of time that the client expects the transition to the new state to take. The interval format must be used to specify this time-out period. A value of 0 or Null indicates that the client has no time requirements for the transition. If this property does not contain 0 or Null, and the implementation does not support this parameter, a return code of 4098 ("Use Of Timeout Parameter Not Supported") is returned.
