Milestone:  Boost 1.40.0                 |   Component:  asio          
  Version:  Boost 1.39.0                 |    Severity:  Problem

-----------------------------------------+----------------------------------
 The {{{expire_from_now()}}} method assumes that 'now' is UTC time which is
 completely discouraging.

 Consider the following sample program:
 {{{
 #include <iostream>
 #include <boost/asio.hpp>
 #include <boost/date_time/posix_time/posix_time.hpp>

 int main(int argc, const char* argv[])
 {
         using namespace std;
         using namespace boost::asio;
         using namespace boost::posix_time;

         io_service service;
         deadline_timer timer(service);

         cout << "current UTC time is '" <<
 to_simple_string(microsec_clock::universal_time()) << "'" << endl;
         cout << "current local time is '" <<
 to_simple_string(microsec_clock::local_time()) << "'" << endl;
         timer.expires_from_now(minutes(1));
         cout << "timer is set to expire at '" <<
 to_simple_string(timer.expires_at()) << "'" << endl;

         return 0;
 };
 }}}

 It produces the follwing output:
 {{{
 current UTC time is '2009-Aug-03 12:11:41.775770'
 current local time is '2009-Aug-03 19:11:41.782770'
 timer is set to expire at '2009-Aug-03 12:12:41.791770'
 }}}

 I believe the output should be:
 {{{
 current UTC time is '2009-Aug-03 12:11:41.775770'
 current local time is '2009-Aug-03 19:11:41.782770'
 timer is set to expire at '2009-Aug-03 19:12:41.791770'
 }}}
