Q: What is the DST solution for VC++ 6.0 app using _timezone variable? Are we going to gat a patch from you? or we have to make code changes? also how will we test before/after scenarios?
A: Sorry, VC++ 6.0 is unsupported and will not have a patch. You should be able to test scenarios in a closed lab environment by simply altering the system date/time. KB932955 (http://support.microsoft.com/kb/932955) has all the Visual Studio DST information for you.
