The type C<double> is used to represent timestamps. It is required to
have at least 51 bits of mantissa (and 9 bits of exponent), which is good
enough for at least into the year 4000. This requirement is fulfilled by
implementations implementing IEEE 754 (basically all existing ones).
implementations implementing IEEE 754, which is basically all existing
ones. With IEEE 754 doubles, you get microsecond accuracy until at least
2200.
