I wrote a simple program attached. It basicly converts the value from time()(call it A) to tm structure, then converts this tm back to a value in seconds using tzset() and mktime()(call it B). A and B are supposed to be equal. Cygwin gives me a 6 hours difference(I am in Central Time Zone), while other systems(I tried IRIX, Linux, Sun OS) work well. Hope you can give me a hint!
