Within vs In

Oh, my bad, sorry. I won't let it happen again
Please, can you tell me the answer?

What do you mean by "quote you on it?
Moreover, what are the differences between ( or among? need help here) "Before and hour", "Within an hour", "In an hour", " After an hour"?

What Riverkid meant by "don't quote me on it" is that it is not cut and dried. For example, I might say I will be there in an hour, but--do you get the idea?

Use "before an hour" in a sentence and I can tell you what I think. I agree with Riverkid's analysis of "within an hour" vs. "in an hour". I also don't think there is a whole lot of difference between them practically speaking.

How would you use "after an hour" in a sentence?

Ah, I think riverkid said that I should not quote his post in order not to let his involved in arguments. Is it right?
I would use "after an hour" in such a sentence:
I'll be at your house after an hour, John

Maybe. Maybe not.

I would use "after an hour" in such a sentence:


I'll be at your house after an hour, John

after an hour
Why does my computer shut down after an hour or two of playing music from my external drive?
Can I automatically send out emails after a specific time, such as after an hour, or a day etc?
After an hour or two, right click won't open anything, nor can I open programs with one click.
That feeling disappeared after an hour of PowerPoint presentations and discussion.
Sketch your diagram for "after a few minutes" at the left and after an hour at the right.

Look like that helps a little bit, thanks, Ronbee.
But what's the difference between "is it right?" and "is that right?"

If we are referring to a past time situation, in an hour means within the hour in question:

My boss thought it would take longer, but I completed the report in half an hour yesterday afternoon.


He wrote the novel in six weeks last summer when he was on holiday in Florida.
If we are referring to a future situation, in an hour normally means after an hour has passed and can be used as the simpler alternative to in an hour's time. Compare the following and note how the preposition changes when we use a negative construction:

It'll be ready in about half an hour.

It'll be ready in half an hour's time.

It won't be ready for half an hour.


I'll see you again in six months.

I'll see you again in six months' time.

I shan't see you again for six months

If "in an hour" means "within an hour" in the past, how can we express "after an hour" in the past?
Oh, I thought "after an hour's time" would mean "within an hour"?
