The moods in English are divided into five categories: declarative mood, imperative mood, subjunctive mood, interrogative mood and exclamatory mood. The subjunctive mood is used by speakers to express assumptions, or situations that are difficult to achieve, rather than objectively existing facts. What is stated is a condition, not necessarily a fact, or even completely contrary to the fact.

In addition, if you need to express subjective wishes or some strong feelings, you can also use the subjunctive mood. The subjunctive mood is expressed by a special form of the predicate verb. The subjunctive mood is used when expressing imaginary situations that are false, contrary to facts, or difficult to achieve. The subjunctive mood is also used when expressing subjective wishes or some strong emotions.

That is, when a person wants to emphasize that what he or she is saying is based on his or her subjective thoughts, wishes, assumptions, guesses, suspicions, or suggestions, rather than on objective reality, the subjunctive mood is used. Mainly an expression of English grammar.

Conditional sentences can be divided into two categories, one is true conditionals and the other is unreal conditionals. Unreal conditionals express hypothetical or actual situations that are unlikely or even completely impossible, so they use the subjunctive mood.

When the verb wish is followed by an object clause, the predicate of the clause must use the subjunctive mood. If you want to express a wish that is contrary to the current facts, use the past tense or past continuous tense as the predicate of the clause (same as changing the verb be to were);

If you want to express a wish that is contrary to the past facts, use the past perfect tense as the predicate of the clause When had done (note that the modal verb here cannot use should); if it expresses a wish that is uncertain or unlikely to be realized in the future, use would (could) + the original form of the verb.

The applied sentence pattern of the attributive is It is or was(high)time?that+complete sentence. The predicate verb form of the sentence is in the past tense or should do form and the should cannot be omitted.
