Moment - a medieval unit of time equal to 90 seconds
In the Middle Ages the "moment" was understood as a very specific unit of time - 90 seconds, no more, no less. And in our time, the concept of "time" has become somewhat more vague.
For the first time the term "moment" used John Treviso 1398th year, writing that one hour consists of 40 points. But nowadays this word denotes a very short period of time, but its original meaning, no one remembers.
