Comment (by matt@…):

 I just wanted to clarify the cause of the bug here:

 posix_time exposes classes (hours, minutes, seconds) that take a "long" as
 their constructor. These parameters are passed through to the internal
 time_resolution_traits and stored in a "v_type" which is int32_t in the
 default template parameter construction.

 On LP64 platforms (64-bit except Windows), long and int32_t are not the
 same size. The time_resolution_traits default type for "v_type" should
 probably be upgraded to use a "long" since this could be done without
 changing the external interface to posix_time.
