I believe that _someone_ at _some point_ will have to make that
assumption though.
Unless they want to have some ugly user-interface mess like
every stream initially showing as "created 1970" to the suddenly
jump to the correct value.
Either way, the short of it is that I can't see that 0 as an
initialization value will cause anything but annoyance long-term.
INT64_MAX hopefully only long beyond the time we would care about.
And UINT64_MAX means you have to be careful to not involve anything
signed at any point, unless there's a good reason I'd prefer sticking
with INT64_MAX (and ideally some error handling if the received
timestamps should be >= than that).
