Good point. The way BSD people look at this issue - 3rd party apps are sort of out of consideration.

I think they actually consider it to be self-contained.

[UPD] But I haven't checked how NetBSD handled y2038. It might be that they didn't break the ABI. In some parts, I think, OpenBSD/FreeBSD/NetBSD just converted time_t to an unsigned 32-bit int.
