How to put the label on the other side of the interval. 

For instance in the following code, how to push the label **End** on the other hand. 

    displayLaTeX[string_] := 
     DisplayForm[ToBoxes@
        TraditionalForm@ToExpression[string, TeXForm, HoldForm]];
    TimelinePlot[{DateObject[{2016, 3, 6}] -> 
       Row[{"Start ", displayLaTeX["\\sum_{i=0}^{10} f(x_i)"]}], 
      Interval[{DateObject[{2015, 6, 1}], DateObject[{2016, 2, 29}]}] -> 
       "End ", {Interval[{DateObject[{2015, 1, 15}], 
         DateObject[{2015, 9, 9}]}], DateObject[{2016, 7, 31}], 
       Interval[{DateObject[{2016, 7, 27}], DateObject[{2016, 8, 6}]}]}}, 
     AxesOrigin -> Center, PlotTheme -> "Classic"]
