It's a TeX-ism.  Rd2dvi writes \today. You can redefine that macro in
your Rd.cfg file. The standard definition is

\def\today{\ifcase\month\or
  January\or February\or March\or April\or May\or June\or
  July\or August\or September\or October\or November\or December\fi
  \space\number\day, \number\year}

which suggests

\renewcommand{\today}{\number\day\space\ifcase\month\or
  January\or February\or March\or April\or May\or June\or
  July\or August\or September\or October\or November\or December\fi
  \space\number\year}

is what you want.

By the way, I believe the actual international standard is 2000 June 15,
even if no one uses it. `International' seems to be re-defined in the US!
