This is apparently not a bug in Ruby, but a change in the behaviour of
the DateTime.jd method. DateTime.jd will no longer accept a fractional
Julian Day number if any of the subsequent parameters are specified.

I've made a change in svn (revisions 314 and 316 in the 0.3 branch) to
support the new behaviour of the DateTime.jd method. This will be
included in the next TZInfo release.

Kind regards,
