it is time that 句型中跟过去式,当动词是be动词时,过去式用was还是were?

it is time that 句型后过去式用 was 还是 were 都可以,
但要看接后的宾语从句决定：
The people are still in the dark about this.It is time that the announcement was made.
People are very worried about the lack of action.It‘s time that their minds were set at ease.
（同意楼上说的,that 一般可以省略）

that可省略，time可由high,about修饰，从句中的谓语动词有两种形式，或者用动词的过去式(be用were)；或者用shoud + 动词原形（should不能省略)。此句型为虚拟语气句型，表示“现在某人该做某事了”。含有该事早该去做而未做，现在去做似乎都为时已晚的意思。例：
It';s time （that）we went to bed.
我们该去睡觉了。 ...

当be动词是 is时，从句的谓语动词用现在完成时，当be 动词是 was 时，从句谓语动词用had dene
