I changed my mind about which tool I want to introduce as a time utility.
pendulum is much better than humanize. Its only doing time related stuff. It's doing one thing and, its doing it well. That was also the intended research of this ticket.
humanize is also nice as it’s providing multiple tools for human display, but for the time display this is a bit annoying since you still have to use datetime which is convenient. humanize can still be kept for later usage in case of a need. Except from the time display, I found one usage in membership displaying three instead of 3. And may be for later, displaying amounts in a localized way (en: 100,000.5, fr: 100 000,5).
The reason why I choose humanize over pendulum is because, pendulum is not yet in Debian. So, I choose the easy way. So, I will try with pendulum for now, if we do not have enough time to package pendulum in Debian, I will find a way, by using datetime, humanize, or something else. That shouldn't be a blocker to start using this nice time library: pendulum.
