The time that the Job was actually started. This time can be represented by an actual date and time, or by an interval relative to the time that this property is requested. Note that this property is also present in the JobProcessingStatistics class. This class is necessary to capture the processing information for recurring Jobs, because only the \'last\' run time can be stored in this single-valued property.
