> The "Start Time" column shown on Job History server's main webpage 
> (http://<host>:<port>/jobhistory) is actually showing the *submit* time for 
> jobs.  However, when you drill down to an individual job's page, there the 
> "Start Time" really does refer to when the job actually started.  
> This also true for the web services REST API, where the Jobs listing returns 
> the submit times as "startTime", but the single Job API returns the start 
> time as "startTime".
> The two different times being referred to by the same name is confusing.  
> However, it is useful to have both times, as the difference between the 
> submit time and start time can show how long a job was stuck waiting in a 
> queue.  The column on the main job history page should be changed to "Submit 
> Time" and the individual job's page should show both the submit time and 
> start time.  The web services REST API should be updated with these changes 
> as well.
