You are quite correct that the BIOS time is usually in wall-clock time, and that different operating systems will handle that problem differently. There have been reports that Windows can use a BIOS clock in UTC, but I've never tried that myself. I don't know whether OS-X has the option to use wall-clock time for the BIOS - it would be helpful if it did!
The message was rejected because I used a wrong sender address.
The registry key is:
And then add a DWORD (32bit) value and name it RealTimeIsUniversal with a value of 1
It should be working with windows 8 also, but I don’t use that.
It is advised to set this key on dual boot systems with linux or osx. OSX doesn’t have the option to set the clock to localtime AFAIK.
