Hi, I am using the fracdiff package to estimate the parameters of an ARFIMA(1,d,1) model. I would also like to get the residuals of the series. I have seen another post about this (below). However, being still quite at the beginner level in terms of R, I did not quite understand how this worked. I also read through the fracdiff package manual with no success to find any help with the

A new version of tseries (0.9-10) has been uploaded to CRAN. The new version contains the class "irts" for irregularly spaced time series. Irregular time series are basically time series where each observation (uni- or multivariate) has a time-stamp represented by an object of class "POSIXct". It provides some basic functionality such as reading and writing irregular time

Can anybody give me a hint why as.POSIXlt doesn't recognize the same timezones that zdump knows about (Linux Suse 8.1 and Suse 7.3)? Is there a workaround?
