Is there a format specification for printing such a type or must it first
be converted to long long by either cast or arithmetic?  I'm uneasy with
the idea of an integral type that can't be printed.  Is the format portable?

And what does time_t[] look like?  Might there be slack bits between
members of the array?

But this answers my long confusion about why localtime() requires a
reference, tine_t*, rather than merely a value.  There may be no way
to pass such an (opaque?) type on the stack.
