Few pointers:

- http://cppcms.sourceforge.net/boost_locale/html/appendix.html#why_plain_number
- 
http://cppcms.sourceforge.net/boost_locale/html/dates_times_timezones.html#dates_times_timezones_qna

Few points to differ:

Boot.Locale date_time is:

  a) Provides different calendars (non-Gregorian) like Hebrew, Islamic
     that are frequently used using same interface.

  b) locale dependent (which calendar, what is first day of week)

  c) Time-Zone dependent (for example adding one hour is different from
     changing its posix time by +3600 because of Summer time)

  d) Represents both time and date in same object represented as a POSIX time
 
     Note: ptime is different as it is not really POSIX time it may be local 
     time as well.

Basically Boost.DateTime and Boost.Locale's date_time have very few
in common.

Boost.Locale's date_time is like a calculator of time in current locale.

No, it does not. It is very different.
