Hi @da2ce7 @WarmBeer , this is ready to review.

Hello jose, you may wish to rebase upon: 8746d82
And apply the changes in this fixup: df0a9ee

Otherwise really good docs! :)

df0a9ee can be squashed into 0bf13e6, it adds nothing of value as a interdependent comment.

Thank you, @da2ce7. I've included your commits! Thank you for fixing the comment about the "The year 2038 problem". I searched for the i64 overflow without reading the whole article. My comment was a bit inaccurate. From 15 years (2038 - 20233) to 21 times the universe's estimated age of the universe 🤣.

Many modern systems have been upgraded to measure Unix time with signed 64-bit integers which will not overflow for 292 billion years, which is approximately 21 times the estimated age of the universe.
