Project Server 2013 : How to Change Project owner Using PSI

Question

Hi,
I have the following sets of codes for changing the project owner but both of them have not worked.
1>
private static bool UpdateProjectOwner()
   bool projUpdated = false;
   try
     User newOwner = projContext.Web.SiteUsers.GetByLoginName(Username);
     Guid ProjectGuid = ProjectUID;
     //Console.Write("\nUpdating owner to {1} on project: {0} ...," ProjectGuid, Username);
     DraftProject draftProjectToUpdate = projContext.Projects.GetByGuid(ProjectGuid).CheckOut();
     draftProjectToUpdate.Owner = newOwner;
     QueueJob qJob = draftProjectToUpdate.Update();
     projContext.Load(qJob);
     projContext.ExecuteQuery();
     JobState jobState = projContext.WaitForQueue(qJob, timeoutSeconds);
      QueueJob qJob2 = draftProjectToUpdate.CheckIn(false);
      projContext.Load(qJob2);
      projContext.ExecuteQuery();
      JobState jobState2 = projContext.WaitForQueue(qJob2, timeoutSeconds);
     catch (Exception ex)
       Console.ForegroundColor = ConsoleColor.Red;
       Console.WriteLine(ex.Message);
       Console.ResetColor();
   return projUpdated;
2>
String projectOwnerIDstrNew = Convert.ToString(dr["ProjectOwnerUID"]);                        
String projectOwnerIDstrOriginal = Convert.ToString(project_Ds.Project[0].ProjectOwnerID);
if (!projectOwnerIDstrNew.Equals(projectOwnerIDstrOriginal))
 Guid ownerID = new Guid(projectOwnerIDstrNew);
 project_Ds.Project[0].ProjectOwnerID = ownerID;
 project_Ds.AcceptChanges();
bool managerChanged = true;
Is there any mistake in these above functions ?
If Not, then is there any other way of updating the project owner with help of PSI.

Hi Steve,
Are you talking about PWA or Project Pro?
In PWA: the project has to be checked in first, then go to the "options" tab in the ribbon and unselect the checkbox that allows displaying time with the date.
In Project Pro, it is up to users to set in the date format without the time in file\options\schedule, date format.
In the PDP, date custom fields are displayed by default with time, the only suggestion I could make would be to create an associated custom field equal to your date field with a formula displaying only the date.
Hope this helps.
