Let me guess. Something very similar to what happened to Microsoft
Exchange servers when the first two digits in a 32-bit signed integer
representation of the current date and time (formatted as YYMMDDHHMM)
changed from "21" to "22" as the date became January 1, 2022.

For those who don't immediately realize why that's a snafu: what is
the value of (2^31)-1 when interpreted as a string representation of a
timestamp according to that format, and how does that relate to Jan 1
