请问这是一句什么从句

请问是表语从句吗？
The saddest moment is when l realized that it was just a fantasy.

表语从句
The saddest moment为主语
is为系动词
when l realized that it was just a fantasy为表语从句
when l realized that it was just a fantasy中的that it was just a fantasy充当了realized的宾语，为宾语从句

宾语从句，判断时可以看句子缺什么成分，这句的is和realize后面都缺宾语
