Is it really possible to do that reliably?

Or maybe you meant to catch errors signaled by current-time-string,
and invoke the external command then.  If so, I'd agree.  But we
should then allow customization of the external command's name,
because on Windows it will be something like 'gdate', to avoid calling
the incompatible Windows shell's built-in (which also prompts
interactively for input).
