Paul - thanks. What I hear you saying is that you aren't primarily interested in the "how long ago" question, but more the "when" question. And that when you think about the "when" question, you want a good amount of fidelity.
Is that a good summary? I am trying to understand if you don't find the moment.js style useful because 1) you aren't trying to answer the question it answers (how long ago) or 2) it is answering the right question in a non-helpful manner. For example, one could imagine answering the "how long ago" question using an high fidelity ISO 8601 time *interval* format: https://en.wikipedia.org/wiki/ISO_8601#Time_intervals I am trying to understand and separate the mental model of the user from the format question (which depends on the mental model)... I also wonder if someone has done UX research on the display of date/times @tgeorgeux ?
