First of all, thanks for the detailed suggestion! I will need more time to look through the provided links and think about the ideas.
I will provide one important consideration you missed in the below comment.

Following ISO and other standards is indeed a reasonable idea. However, the standards are not necessarily designed for human consumption. In contrast, Org mode is designed to be read by humans as well, even without Emacs - just as plain text. Design for human consumption is one of the reasons we do provide the redundant information like week day (I personally did find it extremely useful on multiple occasions) and do use spaces, deviating from ISO. The above ISO example is barely readable by humans. Another example from wiki page of ISO 8601 is even worse: R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M And we need to deviate from ISO 8601 anyway. At least, because it does not define time zones, only absolute UTC offsets. So, the ability to conform with the existing formats remains questionable. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
