Thanks, much appreciated! So the model they are comparing with has the earth at the center and not rotating. The sun revolves around the earth in a single day, not a year. That clarifies the contradictions.

The month they mention must be the sun's rotation about its own axis.

Yes, "the other in less than a month" refers to the "solar day", approximately 27 earth days long.
