#4543: ptime: year 2038 problem

     Type:  Bugs                            |      Status:  new       
Milestone:  Boost 1.44.0                    |   Component:  date_time 
  Version:  Boost 1.44.0                    |    Severity:  Problem   
 Keywords:                                  |  
--------------------------------------------+-------------------------------
 At several locations in the code, the number of seconds, minutes, hours,
 etc is explicitly limited to the value range of {{{long}}}, for instance
 in {{{posix_time/conversion.hpp}}}:


 {{{
   inline
   ptime from_time_t(std::time_t t)
   {
     ptime start(gregorian::date(1970,1,1));
     return start + seconds(static_cast<long>(t));
   }
 }}}

 As a result, for example -4260211200 is represented by some ptime in the
 year 1971, but it should be 1835.

 Or, in other words Boost.DateTime has the year 2038 problem.

 Roland
