I assume that this also means there hasn't been much thought about
userspace support above libc?  i.e., how to take a 64-bit time64_t (or
changing the size of time_t) and translating that to a string using
some kind of version of ctime() and asctime(), and how to parse a
post-2038 date string and turning it into a 64-bit time_t on a 32-bit

The reason why I'm asking is because I'm thinking about how to add the
appropriate regression test support to e2fsprogs for 32-bit platforms.
I'm probably going to just skip the tests on architectures where
sizeof(time_t) == 4 for now, since with a 32-bit time_t adding support
for post-2038 in a e2fsprogs-specific way is (a) something I don't
have time for, and (b) probably a waste of time since presumably we
will either need to have a more general solution, or simply decide to
give up on 32-bit platforms by 2038....
