Here's what I discovered: When I edit the config to show "<TimeZoneInfoSerializable> />" and open NT, it will display my correct time zone in settings, but it will be greyed out. If I then close the workspace, it will change the line to "<TimeZoneInfoSerializable />" dropping the extra ">" If I then open it, it will go back to the UTC greyed out problem. Then if again edit it to "<TimeZoneInfoSerializable> />" it will open with my correct zone but greyed out.
I guess I could create some sort of macro that would automatically edit the file every time, but what a pain.
