In the mean time, to get this project done, it looks like I'm editing 60 tiny titles for my one hour video.
I'm not expert in Motion, but if you already have it, give yourself 5-10 minutes to try and publish the Time Date generator. The basic steps are (I'm doing this from memory so the names of things might be wrong):
1. Sart up Motion and choose a new FCPX Generator template project. Set the project settings that match your own project settings in FCPX.
2. Drag the Time Date Generator into the project.
3. Publish all the parameters you might want to change in FCPXby right clicking on them and selecting publish parameter.
4. Save the project. this will ask you for a name and category, which once saved, automatically appear in FCPX.
5. Drag that one new generator to your project, change the duration to fill your whole timeline, and set the parameters to your starting date/time.
