So as you've seen, I've used all three for the same context, so they're very flexible, can be used.

正如你所看到的，我在相同的语境中使用了这三个短语，所以它们非常灵活，可以使用。

Can you... How flexible can you be on times? You said no evenings, but what if I can’t find something open at 3 o’clock? Can you move earlier or later?

经理：你能不能… … 你能准时多灵活？你说没有晚上，但如果我找不到 3 点开门的东西怎么办？你可以早点或晚点移动吗？
