Hi, I downloaded most recent tz data from http://www.iana.org/time-zones, Time Zone Data v. 2014g (Released 2014-08-28) tzdata2014g.tar.gz<http://www.iana.org/time-zones/repository/releases/tzdata2014g.tar.gz> (278.2kb) Time Zone Code v. 2014g (Released 2014-08-28) tzcode2014g.tar.gz<http://www.iana.org/time-zones/repository/releases/tzcode2014g.tar.gz> (174.0kb) After reading the README file and other document, I understand that the gz is for compiling into unix commands that provide various timezone functions, am I correct? If I m correct, does IANA provide a csv/xls download of tz with daylight saving time info for all cities in the world and delta download periodically?
