#7508: Boost timezonedb incorrect Brazil DST specification

     Type:  Bugs              |      Status:  new       
Milestone:  To Be Determined  |   Component:  date_time 
  Version:  Boost 1.51.0      |    Severity:  Problem   
 Keywords:  timezonedb        |  
------------------------------+---------------------------------------------
 Today our applications running in Brazil have the incorrect time. We
 tracked it down to an error in the boost date_time_zonespec.csv
 specification for America/Sao_Paulo. It specifies that the DST change
 starts on the second Sunday of October (yesterday). However, it actually
 starts on the third Sunday (see the attached document from exchange). I
 downloaded the latest version of boost (1.51), and it is also incorrect
 there. Also note that Linux does have the correct time. I intend to submit
 a bug report to Boost, but I don’t know if you prefer if the external
 communication to go through your team.

 Incorrect:
 "America/Sao_Paulo","BRT","BRT","BRST","BRST","-03:00:00","+01:00:00","2;0;10","+00:00:00","3;0;2","+00:00:00"

 Should be (for all BRST):
 "America/Sao_Paulo","BRT","BRT","BRST","BRST","-03:00:00","+01:00:00","3;0;10","+00:00:00","3;0;2","+00:00:00"
