I just stumbled over the same thing when trying to use a boost::posix_time::microseconds() which during the way to a 64bit value will be garbled by calculations around time_resolution_traits because the integer argument is int32_t per default.

I would recommend that you take from the first traits parameter (that is used with the structs time_resolution_traits_adapted64_impl) in date_time/time_resolution_traits.hpp class time_resolution traits instead of

typename v_type = boost::int32_t

you better use

typename v_type = typename frac_sec_type::int_type

since in the end the _res structs are correctly defined as

typedef time_resolution_traits<time_resolution_traits_adapted64_impl, nano, 1000000000, 9 > nano_res;

which would make the 64bit value properly appear.

Otherwise this all is unusable for us since we work with microseconds and nonoseconds since epoch timestamps on wire.

Why do you consider this ticket a showstopper?

This also makes it impossible to use condition::timed_wait(lock_type& m,boost::xtime const& wait_until).

The conversion to time_duration causes an overflow. Apart from that, I've noticed that xtime_get() and xtime_cmp() are broken too (return int).
