[Rd] [R] R-3.4.0 fails test

I have fixed this in R-devel and will port it over to the R release branch in due course.

The underlying issue is that the conversion from POSIXlt to POSIXct uses the local time zone and not the CET time zone. I believe this is a bug, but I will take up that discussion elsewhere.

Meantime, anyone who lives where DST happpens in December who wants to
get through the remaining tests can avoid this one by changing the line

> stopifnot(length(fd) == 10, identical(fd, format(dct <- as.POSIXct(dlt))))
> stopifnot(length(fd) == 10, identical(fd, format(dct <- as.POSIXlt(dlt))))
(which effectively isn't testing anything much)

A less lazy way would be to comment out the relevant lines.
