#4543: ptime: year 2038 problem
 Reporter: Roland Bock <rbock@…> | Owner: az_sw_dude
     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}}}:

   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.
