I think this sentense means that money is very very important for us, so we also must treat very very important about time. We can't stop the time, so I think time is more important than money. Anyway, we must use polite.
2.A stitch in time saves nine....
I think this sentence means that if you do anything early, it will succeed. If you don't do at once, it doesn't succeed.
3.There's no time like the present...
I think this sentence means that if you have a chance to do anything, the chance doesn't come again and again. When you get a chance, you shouldn't miss a good chance. This sentence looks like " Don't miss a good chance."
4. Fashionable late...
I think this sentence means that these days, if you are wearing loose socks, it is fashionable late for me. It became fashionable before about 6 years. For this reason, someone are wearing them, the person had better read some fashion magazines♪
