`boost::posix_time::duration` multiplication/division limited to `int`.

[JohannesWilde]

The operator*(), operator*=(), operator/(), and operator/=() currently only support int parameters [see boost::posix_time::duration].

I tried to use it as follows:

std::uint64_t const timedeltaInTensOfNanoseconds = 2793555578;
boost::posix_time::time_duration const duration = boost::posix_time::nanoseconds(10) * timestamp;
// duration.total_nanoseconds() = -15014117180

[I did define BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG.]

What did work as expected was:

std::uint64_t const timedeltaInTensOfNanoseconds = 2793555578;
boost::posix_time::time_duration const duration = boost::posix_time::nanoseconds(10 * timestamp);
// duration.total_nanoseconds() = 27935555780

Would it be possible to extend the parameter type for above functions to at least support unsigned as well? Or even extend it to 64-bit types? Or make them template-methods [with a concept limiting them to ints and floats]?
