use it this way:

\documentclass{article}
\usepackage{pst-plot}
\makeatletter
\newcounter{xVal}\setcounter{xVal}{0}
\def\psSpecialPlot{\pst at object{psSpecialPlot}}
\def\psSpecialPlot at i#1{\begin at SpecialObj\expandafter\psSpecialPlot at ii#1}
\def\psSpecialPlot at ii #1{\psSpecialPlot at iii#1}

}
\makeatother

\begin{document}

\readdata{\data}{listplot3.data}
\data%% shows how the data is _internally_ represented.

\bigskip
\psset{llx=-1cm,lly=-1cm,mathLabel=false}
\begin{psgraph}[Dx=5,Dy=5]{->}(0,0)(20,20){10cm}{8cm}
   \psSpecialPlot[dotsize=5pt]{\data}
\end{psgraph}

\end{document}

You can write the values for the x axis as #2 (the date) or #4 (time)
