When I try to do this:

M-: (apply #'encode-time (parse-time-string "2018-09-05"))

I get:

Debugger entered--Lisp error: (wrong-type-argument fixnump nil)
  encode-time(nil nil nil 5 9 2018 nil nil nil)
  apply(encode-time (nil nil nil 5 9 2018 nil nil nil))
  eval((apply #'encode-time (parse-time-string "2018-09-05")) t)
  eval-expression((apply #'encode-time (parse-time-string "2018-09-05"))
nil nil 127)
  funcall-interactively(eval-expression (apply #'encode-time
(parse-time-string "2018-09-05")) nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)
