he doesn't seem to know what happened last night.
这句话没错的,不要以为宾语从句一定要之态一致,不一定的.
这句话是说:他(现在)好像不知道昨晚发生的事.

he doesn't seem to know what has happened last night
he didnt seem to know what had happened last night?
好象应该用完成式

doesn't 或者 didn't 都可以,要看具体的语境
如果用does not,一般就是通篇的时态都是现在时,或者在谈话中当事人到目前为止也不知道。
用did not则相反
