You might want to look at the following articles from R News:

  author       = {Brian D. Ripley and Kurt Hornik},
  title	       = {Date-Time Classes},
  journal      = {R News},
  year	       = 2001,
  volume       = 1,
  number       = 2,
  pages	       = {8--11},
  month	       = {June},
  url	       = {http://CRAN.R-project.org/doc/Rnews/}

  author       = {Gabor Grothendieck and Thomas Petzoldt},
  title	       = {R Help Desk: Date and Time Classes in {R}},
  journal      = {R News},
  year	       = 2004,
  volume       = 4,
  number       = 1,
  pages	       = {29--32},
  month	       = {June},
  url	       = {http://CRAN.R-project.org/doc/Rnews/}
