    Fix timezone exceptions on Windows XP.

commit 5cc99806d8886f948c05e097e215d7f923a1f621

    Windows: Get default timezone if there's no default key.
    
    Windows XP doesn't provide a default key, just the TZI returned by
    GetDefaultTimeZone(), so use that instead of throwing if there's no
    default key in the registry. If GetDefaultTimeZone() files, throw: We
    can't safely read the database without a timezone.
