Really we can partially blame posix here for not specifying whether
time_t is signed or unsigned. (If it's unsigned it can't represent times
before January 1, 1970, as the code on the left is doing. And there
_are_ times before then. So I think we have to treat it as signed and go
"32 bit timestamps gotta go away before 2038".)

Linus' opinion on unsigned time_t is here (spoiler: it's "no"):

Why did you remove the comment block in the second patch? (Is it wrong?)
