One thing you could do is to use the 'its' (irregular time-series)
package on CRAN.
e.g. using a trivial dataset
require(its)
its.format(%Y-%m-%d) #defines text format of dates in dimnames
df - data.frame(1:3,(1:3)^2)
dimnames(df) - list(c(2003-01-03,2003-01-06,2003-01-07),letters[1:2])

I don't think so. The POSIX*t classes in R are the most standard,
followed by the chron package and only then the date package.
