It wasn't until … that …和It was until…that…意思相同吗？

这两个句型当然是不一样的。前面是否定形式后面是肯定形式。

第芹并一个it这个形式主语，后面that引导的是真正的主语从句。

第二个句型是强调句。但事实上，通常采用的都是后面一个句型，表示直到…才。具体举例子来说，

他昨天直到晚上12点才拦首消回简知家。

He didn't get home until 12 o'clock at night.

It was until 12 o' clock that he got home.

直到把所有的任务完成，他才离开办公室。 It was until he finished all the work that he left the office.

还没有到中午12点，她就把饭吃完了。

It wasn't until noon that she finished lunch.

直到我们贺搏相禅铅祥处激段了一段时间后才发现我们有那么多的共同点.

这句是固定搭配,It be not until ... that ...

只能用that不能用when
