As I Xi It

For the last couple of years, if I’m still awake in the wee hours, I can hear an alarm go off at 04:24. At first I thought it was an old digital watch, but in my recent room clear out, I found what I thought was the offending article but the battery had died. Just now, I heard the beeping go off at 04:24 again. Whatever it is, it must have a pretty low power consumption to still be tormenting me at 04:24.

It’s a bit of a conundrum.
