 =item C<double> must hold a time value in seconds with enough accuracy
 
 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, which is basically all existing
-ones. With IEEE 754 doubles, you get microsecond accuracy until at least
-2200.
