There is a bug in the Argentine timezone, as not the whole country but parts of it are GTM-2 because of summer time. There is more information available (including a patch) at http://bugs.gentoo.org/show_bug.cgi?id=245283 My best regards, -- Ricardo I. Vieitez

FW: RE: How to determine whether the OS has the latest DST rules

I'm forwarding this message from Phil Guera, who sent it by way of a secure mail server. --ado Florence, I did some programming to read this information. Basically, the information is given in the area that Microsoft calls TZI. It's a complicated element to decipher, but if you give me the timezones you are interested in, I can give you screen shots of the interpretation of the registry binary data. I wrote this TimeZonesExplorer just before Microsoft added some historical capability to their registry's handling of timezones, and never did update it to read the historical data, but the way MS stores the info is based on the zone, current year, and subset of yearly historical data. Though their treatment of historical data doesn't go back in time very far like the TZ database does. I'm still running Windows XP pro, but I believe the registry is structured the same on Vista at this time. At any rate with the screen shots, you should be able to see the basics of how to make the binary data more human readable. It's just a matter of splitting the TZI info into parts and performing some hex math conversion to get to the actual information contained within it.
