perhaps one could typeset it twice:

\documentclass{article}
\begin{document}
\newcommand{\timetask}[2]{#1\\ \kern\offset #2\\}
\newcommand{\foo}{%
  \begin{tabular}{ll}
    \timetask{08:00}{breakfast}
    \timetask{13:00}{lunch}
    \timetask{17:00}{dinner}
  \end{tabular}%
}
\newdimen\offset\offset=0pt
\newbox\tbox
\setbox\tbox=\hbox{\foo}
\offset=0.5\wd\tbox
\begin{center}
\foo
\end{center}
\end{document}
