I suspect it's a sequence number that advances monotonically on at hardware controlled tick rate which is used as a simple high-watermark for establishing recency and probably (subsequently) ordering, and this thing is probably a 32bit integer or some slice of a 64bit one and after being online for ~51 days it nears the threshold of rolling over, which would then cause the receiver to never show new data because it thinks its very, very old data.

That was my first thought as well. The Arduino millis() function wraps back around to zero at around 50 days of uptime. https://www.arduino.cc/reference/en/language/functions/time/...
