好像不是恰当的时机，我觉得有点突然

老外说他们不大这么讲的，非要翻译的话，就是：it seems suddenly as if it's not a proper time
联系你的上下文，也可以考虑一下使用， too sudden to decide， 类似这样的。

it seems not the right time, I think it is too suddenly

I feel all of a sudden, and it seems not at the right time.

It is kinda sudden, i dont think it is the right time.

I do not want to rush, because I think it is not the right time.

it seems too sudden to be a proper time for me.
