Really? I'm not sure if this is bait or not, but 64b time_t extends the epoch over 200 billion years into the future. I figure we'll handle it in Linux 7.0 or 8.0 at the earliest :P

It's probably not bait. It's easy to intuitively think 64 bits is only double. I do these calculations regularly as security professional (password strength for example) but not everyone does.

Well, 64 bits is often used with nanoseconds, and 32 bits is in seconds, so it's a bit more complex than it seems.
