R has no such classes. S-PLUS has "its" and "cts" and now has other classes
for calendar time series.  It makes almost no use of those classes though,
except to plot them.  It is unlikely that we will be adding such classes to
R unless they go with something useful to do with them, and if we do they
will need more structure than "its".
