I wanted to modify my first suggestion.
Perhaps a better idea would be to reference an external document
giving an overview of the subject.
I couldn't find a discussion of POSIXct/POSIXlt objects in the R
manuals (unless I missed it somewhere), so perhaps "An Introduction to
R" could be updated to include this subject, and then the help files
could reference that?

Mark Leeds has already mentioned one possible (unofficial) source.
And I suspect that there are others.

Not entirely unofficial as it waw published in R News:

   title={R help desk: Date and time classes in R},
   author={Grothendieck, Gabor and Petzoldt, Thomas},
   journal={R News},
   volume={4},
   number={1},
   pages={29--32},
   year={2004}
}

I should have mentioned that it was in R-news. My mistake. Thanks Luke for
clarification.
