Thanks for the results, Jim.  You're right that the digits are there,
the subtraction above proves it.  But why wouldn't they print?  They
are Floats.  Float#to_s prints digits (e.g. the literal 1.5).

It is as if the results from Time.to_f are singleton objects whose
#to_s has been rewritten!

I wish there was a way to know if an object is a singleton or has
otherwise been structually modified.
