When was the death of Yohanan Ben Zakkai?

This answer I saw is unfortunately complete nonsense:

"He died aproximately 100 years before the destruction of the second Bais ha'mikdosh"

Bais Hamikdosh is the Ashkenazic pronunciation of Bet Hamikdash, meaning the Holy Temple of Jerusalem.

Yohanan Ben Zakkai was a commander in the defence of the Temple in the siege against the Romans.

He established the Yavneh Generation, "Dor Yavneh", founding the first official school of Rabbinic Judaism.

Rabbinic Judaism teaches life based on interpretations of the Torah in the Mishnah and Talmud - all the works of Scholars and Rabbis, but none of which is considered Divine, which Torah is.

Rabbi Yohanan died in Yavneh probably a few years after 100 CE/AD
