I'm not Evgeny, but I think it's because the titular time spec includes
defaults set by decoded-time-set-defaults:

  (parse-time-string "11:30")
  ;; => (0 30 11 nil nil nil nil -1 nil)

  (decoded-time-set-defaults (parse-time-string "11:30"))
  ;; => (0 30 11 1 1 0 nil -1 nil)

Here's the context: https://emacs.stackexchange.com/q/64686/15748

Ah, I missed the last part in the docstring of encode-time:

  Years before 1970 are not guaranteed to work.  On some systems,
  year values as low as 1901 do work.

So I don't know whether my suggested use of decoded-time-set-defaults is
wrong, or whether that function should set the year to 1970, as might be
assumed from its docstring.

Thanks,
