What do we usually mean by a few minutes in life? It's just that your meaning has been misinterpreted. It is correct to say that it is a few minutes past the hour. Perhaps it seems to express a concept of duration in the language, but what we think of as an hour and a few minutes is also a representation of a time point. For example, if you ask what time it is, others will answer it a few minutes after the hour, which is the time indicated at that time. I hope my answer is helpful to you.
