R devel - Nov 2004 - error in chron object library

Times series of rain and discharge in hydrologic - stations has above 95
years of daily records.
In the temporal series over "serie" dataframe, using chron's
object:
> library(chron)                          # load chron library 
> length(serie$data)
[1] 27182
> serie$data[length(serie$data)]
[1] (85-12-31 00:00:00)                   # 1985-dez-31 00:00:00hs
> serie$data[1]
[1] (11-08-01 00:00:00)                   # 1911-aug-01 00:00:00hs
> serie$data[length(serie$data)] -serie$data[1]  # error, correct value
is: 27181

which are the solution?

I guess you get something negative,because the year you have coded is 
2011 rather than 1911!
But I cannot be sure because you have not specified any reproducible 
example. Also, you have not said what the error message is. Which 
version of R, chron and the OS? Please read the posting guide!
