Is it always a signed integer? Can't it sometimes be unsigned?
This is the "year 2037" problem, where 32-bit unsigned time rolls over.
However there is also a "Year 2106" problem, which is where 32-bit
unsigned time rolls over. I think there *are* some systems where it's
unsigned, but still 32 bits. Or at least there are apps where that is
the case.
