#9489: boost::date_time::time_resolution_traits uses 32-bit seconds for 64-bit
systems

 Reporter:  mreissne@…        |      Owner:  az_sw_dude
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  date_time
  Version:  Boost 1.54.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 boost::date_time::time_resolution_traits defaults to boost::int32_t for
 its v_type parameter.  This means that for 64-bit systems, such as
 time_resolution_traits_bi64_impl and
 time_resolution_traits_adapted64_impl, date-times whose seconds count
 exceed the int32_t limit will overflow, returning a negative value for
 boost::posix_time::time_duration::total_seconds.

 The attached file reproduces the issue.  The output on a 64-bit Intel(R)
 Xeon system running Linux is:

  2038-Jan-19 03:14:08
  -2147483648

 We have found that changing the v_type definition from boost::int32_t to
 typename frac_sec_type::int_type resolves the issue by associating v_type
 with its implementation's definition.
