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

I have just found the solution.
We have a custom Linux distribution that allows us to have several R (+
glibc and others) versions in parallel for tools related to our job domain.
We have another etc/ folder for those tools and R looks for the
localtime file there, not in /etc/.
So linking /etc/localtime to our etc/ folder makes R happy and
x <- as.POSIXct("2002-02-02 02:02")
