BTW: when using 64 bits isn't it usual to store signed milliseconds as
opposed to unsigned seconds?

Or maybe I'm a bit influenced by Java, but being able to represent any
time in the long past or long future to millisecond accuracy seems a
nice bonus to me (and costs pretty much nothing), whereas an unsigned
second value starts unnecessarily in 1970 and goes on in the future way
too much.

I don't remember what does 64bit-milliseconds reach, but it was in the
many-thousands-years, having many-millions-years using 64bit-seconds
seems a bit far too stretched ;-)
