Milestone:  To Be Determined     |   Component:  date_time 
  Version:  Boost 1.45.0         |    Severity:  Problem   
 Keywords:                       |  
---------------------------------+------------------------------------------
 we encountered an overflow in posix_time::microseconds:

 //about 40 years (1970-2010)
 const __int64 n = 1267195987000000;
 boost::posix_time::microseconds td(n);  //overflow

 The overflow is easy explainable since date_time::subsecond_duration first
 multiplies it causing the overflow and then divides by 1000000.

 There are already multiple posts spended on this.
