到了做..的时间(强调没有做/发生)

It's time he was here. (这个时间)他本该到了。(实际没到)
It's high time he (should) go home now, but he doesn't go home.

一.it is (high) time that... ...

It is high time we went home now.

从意义上讲，这个句式没有任何were式虚拟的意味，但是最流行的用法是在其从句中使用一般过去时态。虽然这个句式有很多be式虚拟的意味，而且也可以使用should do的形式，但是远不如用过去时态的形式更为流行和普遍，建议最好使用一般过去时态的形式，少用should do的形式。

我建议，大家在理解和运用it is (high) time that...句式的时候不要把它理解成虚拟语气，只是把它当作一个特定的句式就可以了，这样掌握起来反而便利得多。建议的要点有二：

1、在 it is (high) time that...从句中尽量使用一般过去时态这种形式。

2、在 it is (high) time that...从句中如果使用了should do 的形式，要注意这个句式中的should 一般不省略。

二 it is time to do强调现在,不含虚拟的意味,例如:
It's time to go home,please be quick.
