In my latest MS, my editor has changed all my times to numbers (e.g. instead of ten o'clock, she's changed it to 10AM). I'm curious how you all write times in your stories, and how you prefer to see them in stories you read. Personally, I haven't got a strong opinion, but I'm quite certain I started writing my times out based on some advice or editing I'd received somewhere along the line. So what do you think? Is it ten o'clock, or 10AM?
