[R] as.POSIXct character string is not in a standard unambiguous format

[Sebastien Moretti]

Hi Ben

Thanks for your answer
I have already tried this, as well as
     x <- as.POSIXct(strptime("2002-02-02 02:02", "%Y-%m-%d %H:%M"))
It works! But it does not fix it widely for all tests used during the 
"make check" step at compile time. Unless I patch all of them.

There is something with localtime but I cannot find what.

On another machine with another Linux OS, and the same environmental 
variables
    x <- as.POSIXct("2002-02-02 02:02")
works fine.
