There is a new chronology.sty by Levi Wiseman. The documentation (pdf) says:
Most timeline packages and solutions for LATEX are used to convey a lot of information and are therefore designed vertically. If you are just attempting to assign labels to dates, a more traditional timeline might be more appropriate. That’s
what chronology is for.
Here is some example code:
\documentclass{article}
\usepackage{chronology}
\begin{document}
\begin{chronology}[5]{1983}{2010}{3ex}[\textwidth]
\event{1984}{one}
\event[1985]{1986}{two}
\event{\decimaldate{25}{12}{2001}}{three}
\end{chronology}
\end{document}
Which produces this output:
