>From my previous correspondence with Microsoft about bugs in their
C library implementation of timezones, I can tell you that what TZEDIT
tells about NT's knowledge of timezones may have no bearing on what
the C library does. The implementation of timezones in the OS itself,
and in Microsoft's proprietary API for accessing this info seems to be
bug free, it is their C library that is buggy.
