[R] ISOdate returns incorrect date?

[Simon Fear]

I've been using the following little `helper` function:

tea <- function() {
 shell("C:\\program files\\kettle\\tea.exe /2sugars", wait=FALSE)
}

I was thinking of submitting it to CRAN until I discovered that
when I ran it on my laptop on holiday in Italy, it made coffee!
I reluctantly decided not to submit it, given that relying on the 
OS, and particularly its timezone settings, obviously wasn't 
robust enough for a cross-platform implementation.
