Thanks George. I was just doing some testing along the same lines as you to see if I could find a pattern. I found the same kind of thing you did where Eastern Time (US&Canada) (GMT-05:00) works fine and Indiana (East) (GMT-05:00) causes a crash.

DST sounds like a good guess to me ... it's better than anything I have at the moment. <g> Anyhow, I hope you're able to find something out ... let me know if there's anything I can do to help. Your code will come in really handy for a data synchronization project I'm working on if we can get this sorted out.
