it is the time that从句是什么时态呢？
It is time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。这个句型可以用在作文结尾，表达一种号召或提议。意为“到了该做......的时候了”。
It is time that the children went to bed.
It is time (that) 后所接的从句采用的时态是did一般过去时或should do其中的should不省略的两种形式。
It’s (high/ about) time (that) + 主语 + did
It’s (high/ about) time (that) + 主语 + should do
事实上，It’s (high/about) time (that) 后所接的从句还可以使用四种其他形式
It’s (high/ about) time (that) + 主语 + ought to do
It’s (high/ about) time (that) + 主语 + was/were doing
It’s (high/ about) time (that) + 主语 + could do
It’s (high/ about) time (that) + 主语 + do
It's (high/ about) time (that) + 主语 + are doing

相关用法：It's the first time that句型
一、结构：
这是一个固定句型。“这是某人第一次做某事”
It is the first time that ... has/have done sth.
二、用法：
一个特殊的句型强调句，主要考察that后面的用法。一般说来，在It [This] is the first time＋that-结构中，that-从句通常用现在完成时：
例：It was the first time that she had sung in public.
那是她首次公开演唱。
It was the first time that she had lived independently.
那是她第一次独立生活。
若It was the first time that-结构中,that-从句通常用过去完成时,有时也用一般过去时,有时若有包括现在在内的时间状语,偶尔还可用现在完成时：
例：I was lucky because that was the second time I (had) visited Japan that year.
我很幸运,那是我那年第二次访问日本。
it is the time that从句是一个由it做形式主语的被省略了主语的现在时的陈述句。因此，从句的时态取决于主句。例如：
It is the time that we should start. (主句是现在时，从句也是现在时)
It was the time that we should have started. (主句是过去时，从句是虚拟语气的过去时)
It will be the time that we can start. (主句是将来时，从句是将来时)
