Darkness leads me to this bug under the pale moonlight 
But as a general tip, it would be definitely better if there is a link or screenshots. I can hardly understand what you are talking about if I haven’t translated the documentation 
Embed comments:
The problem is in embed/comments.html.erb:
https://github.com/discourse/discourse/blob/master/app/views/embed/comments.html.erb#L13
then ember_helper.rb:
https://github.com/discourse/discourse/blob/master/app/helpers/embed_helper.rb#L3
The fix can be either using the FreedomPatches::Rails4.distance_of_time_in_words, I18n.localize(dt, format: I18n.t("datetime_formats.formats.short_no_year")) or replace the link by a different translation string as the digest email.
; I don’t quite understand the current status of server time formats so I won’t fire PR here.
