@@ -5050,8 +5050,12 @@ 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 with millisecond accuracy (the design goal for libev). This requirement is overfulfilled by -implementations using IEEE 754, which is basically all existing ones. With -IEEE 754 doubles, you get microsecond accuracy until at least 2200. +implementations using IEEE 754, which is basically all existing ones. + +With IEEE 754 doubles, you get microsecond accuracy until at least the +year 2255 (and millisecond accuray till the year 287396 - by then, libev +is either obsolete or somebody patched it to use C<long double> or +something like that, just kidding). =back |
