+  If x is any Date object whose milliseconds amount is zero within a
+  particular implementation of ECMAScript, then all of the following
+  expressions should produce the same numeric value in that
+  implementation, if all the properties referenced have their initial
+  values:
+
+  x.valueOf()
+  Date.parse(x.toString())
+  Date.parse(x.toUTCString())
+  Date.parse(x.toISOString())
