Subject: bug#40861: 26.3; parse-time-string does not intepret times
Date: Sun, 26 Apr 2020 19:59:07 +1200

Hi,

I have noticed that (parse-time-string s) is not working properly for
time strings, INCLUDING provided examples in the manual.

I first noticed it on org-mode; and tested it with (org-read-date) which
uses (parse-time-string) to interpret times.

I suspect there is some bug in =parse-time-rules=.
Scratch buffer to replicate the issue is provided below.

Kind regards,
Roger

;; *scratch*
;; org.el
(require 'org)
org

(org-read-date nil nil "14:00")
"2020-04-26"

;; parse-time.el
(parse-time-string "14:00")
(nil nil nil nil nil nil nil nil nil)

;; Provided examples from the manual
(parse-time-string "Fri, 25 Mar 2016 16:24:56 +0100")
(nil nil nil 25 3 2016 5 nil nil)

(parse-time-string "1998-09-12T12:21:54-0200")
(nil nil nil nil nil nil nil nil nil)
