How do you get POSIXlt objects into a data frame?
> df <- data.frame(x = as.POSIXlt(as.Date(c("2008-01-01"))))
> str(df)
'data.frame': 1 obs. of 1 variable:
$ x: POSIXct, format: "2008-01-01"
> df <- data.frame(x = I(as.POSIXlt(as.Date(c("2008-01-01")))))
> str(df)
'data.frame': 1 obs. of 1 variable:
$ x: AsIs, format: "0"
