I don't much care which one we choose, to be honest. I kinda doubt that #b
will have more compatibility issues than #c, and find conceptually
cleaner by a thin margin: a non-Date object isn't an invalid Date, it's not
a Date. But then again, if you don't want an object to be treated as a
Date, don't call Date's toString on it? Implementation-wise, it's pretty
much a wash, at least.
: and for all I know there might be content out there that relies on an
exception being thrown if Date#toString is used on a non-Date object ...
