Micro-challenge: Special Event

[EdS2]

Ah, I was thinking of a palindrome: 2022-12-22 21:22:02... but probably they turn up more often. And as ever, one sees variability in date formats.

So the base 3 observation is nice for being date-format neutral!

And the idea that it won't happen for a long time is subtle - it doesn't say that it hasn't happened more recently! John could have posted three days earlier, but no earlier than that...
