I'm not sure that's it: R uses doubles for its POSIXct values so those aren't at play here. (And even if they were, 64-bit R wouldn't help: that's only pointer size)
One can trace the problem out of xts down to ISOdatetime(2035:2040, 12, 31, 23, 59, 59.999) which is a base R function, but I'm still following it down further. ? DateTimeClasses suggests that OS faculties only rightly control DST up to 2037, so that might be as far as we can understand it.
