Hi Yves I have implemented two functions which use the tz database. They are original code written in standard C++, that are based on internal tables read directly from tz gz files. 1) SetWT(const string &zonename, const RDTime &wt) 2) SetUT(const string &zonename, const RDTime &ut) The first takes a current zonename (ie: 'America/Montreal') and its wall time and fills a data structure with the matching wall, standard and ut times with zone strings ('EDT','EST') The second is the same, except that it takes a local zonename and the current ut. Combined, these two functions can convert any datetime in the past/future to another datetime in a different zone. I'd show you the code but unfortunately they are part of a series of commercial products. But perhaps I can give you some input on how it was implemented, or if there is enough interest I could convince the boss to release licenced lib files for a small cost.

Hi,
I'm currently implementing an API for the tz database that should look like .NET's TimeZoneInfo class to replace that in my application. The API includes: ....
