;;; Commentary:
 | 
						|
 | 
						|
;; I was making some API calls where a URL needed a `since` parameter that of an
 | 
						|
;; RFC 3339 encoded string.
 | 
						|
;;
 | 
						|
;; Because I didn't know what a RFC 3339 encoded
 | 
						|
;; string was at the time, and because I didn't know what its format was
 | 
						|
;; according to strftime, and because I'm most likely to forget both of these
 | 
						|
;; things by the next time that I need something similar, I decided to write
 | 
						|
;; this package so that I can accumulate a list of common time encodings.
 | 
						|
;;
 | 
						|
;; Thank you, Emacs.
 | 
						|
;;
 | 
						|
;; p.s. - I may turn this into a proper module and publish it.  But not today.
