"Most significant" in practical, every day life means just "what I need to know more". I have never heard anyone saying "let's meet at 30 seconds, 12 minutes, and 15 hours", or just "at 12 minutes and 2 hours". Please, everyone understood you are attending engineering, but don't make yourself look dumb like this, because one thing is how maths works, and another thing is the way you need to read numbers for your everyday life purposes.
