Not wanting to put words in Andrew's mouth, but I thought the point of
those changes was that timestamps emitted into JSON should be formatted
per some ISO standard or other, and said standard (almost certainly)
doesn't know what infinity is.

At the same time, there is definitely no such requirement in the JSON spec
itself, so at least the error message is quoting the wrong authority.
