Use ‘it’s time’ with the past simple to talk about an action which finally is taking place, or should take place soon. It always refers to an action or state that should have taken place before the moment of speaking.

Variations on ‘It’s Time’

There are two uses of ‘would rather’ to express hypothetical situations:
Would Rather + Base Form of Verb
Would Rather + 动词原形
Use ‘would rather’ + the base form of a verb to talk about our preferences in the present or the future:
He’d rather his employees work less overtime.
I'd rather leave now.
Jack would rather take a different approach.
In each of these cases, the phrase with 'would rather' shows that another action is taking place than the preferred action of the subject of the sentence.
Would Rather + Past Perfect
Would Rather + 过去完成时
Use ‘would rather’ + past perfect to express hypothetical situations in the past:使用
‘would rather’ +过去完成时表示过去的假设情况：
They’d rather they hadn’t spent so much on the marketing campaign.
Mary would rather she had chosen a different position.
We use ‘wish’ to talk about situations we’d like to change. In this sense, ‘wish’ is very similar to the second or third conditionals because it poses an imaginary situation.
Wish for Present Situations
When we are wishing for a change in a present situation, we use ‘wish’ plus the simple past.
The director wishes he could attend the presentation.
They wish he concentrated more on his work and less on his hobbies.
Wish for Past Situations
When we are speaking about a past situation in a present moment, we use ‘wish’ plus the past perfect.
