andrew,

Not so long ago (20 Nov 02) you wrote to me:

You're welcome :)

I found this function in MSDN, it converts "libc" handle into the
Win32 HANDLE. I think I had the same problem before I wrote that code,
though not sure. It was about 2 years ago.

I have compiled and run your code and it works just like in Borland. So,
the only idea why it doesn't work for you is that your cygwin use crtdll
version of MinGW rather than msvcrtl. crtdll is very buggy. At least there
are bugs with the stat function which returns the times with one hour
difference for the different DST (i.e. at winter you get incorrect time for
the summer files and vice-versa), and with localtime - it is always switch
DST accordingly to the US standard regardless of Control Panel settings.

WBR, Alexander
