I was doing the late shift on a trading floor at a big bank.

The head of the derivatives tech support team pointed out it was about to hit so we opened up a shell and did a "watch" command + outputting the "date" command in epoch seconds and watched it happen.

Then we went back to working.

I remember that moment! I was out at a bar or something at the time but I was prepared and had my laptop with me haha. I was mashing the up arrow and enter to make sure I didn’t miss it.
