Well,
12:34:56.7/8/9 came and went, but (as far as I am aware), nothing truly calamitous occurred on the cosmic scale.
Oh, well. Never mind. Disappointment is my middle name, after all (not to mention patience being my primary weapon).
Meanwhile, did the Earth move for you?

And, lastly, as I was mentioning famous mathematicians, how about one from more recent times (but sadly no longer with us), namely Paul Erdos?* Not a well known name, perhaps ... but a
Genius Guy nevertheless. And, I would say, a true follower of the Cynical traditions.

I can't give you the link, because of the non-standard (Hungarian) characters in the name. But, if you're interested, just go ahead with entering Paul Erdos in Google.
