1. Create an Entity with time periods. There are 12 monthly periods, some are more than 30 days and some less.
2. Create A Roadmap, and associate Projects to the Roadmap.
3. Access Advanced Reporting, and run the Roadmap Timeline report. Populate the designed Options, and run the report.

Some of the monthly time periods are duplicated in the report, so all twelve do not display
