this is a very well known problem.
IIRC, the rationale to the original 1988 POSIX.1 standard
mentioned this, and postulated that the “solution” was the
world would be 64+ bits by then (or that at least «time_t»
would be ... I'll try to remember to check my hardcopy next
week (it's at work)). at any rate, I know _I_ had adb(1)
tell me the End of Time for me in 1987 or earlier; and I
cannot have been the first. check Risks?
whether or not that postulate is “correct” is questionable,
as it presumes (i) most of the world's *ix-based software is
updated before then (with a fix, 64-bit «time_t» or other);
and (ii) it's a serious problem. as with the 2Kyr and DST
defects (assuming USAian Federal Summer Time rules for c.1980
apply to the entire World forever — AFAICR, this one caused a
lump of molten steel to pour onto a factory floor in Germany
a few years ago!) and so on, it doesn't _always_ matter ....
FUD? yes. a problem? yes. serious? maybe (but can
be very annoying!). unknown? NO!
a useful reminder? perhaps, especially since this shows
“well known” ≠ “universially known”.
plans? I only known of the vague “64-bit” thinking,
but have never seen any migration strategy/planning
et.al. written down .... (but I'e also not searched
in years!) .... ?
