If the lunar day is 30 hours and the solar day is 32 hours, and your attempt to count Earth hours is off by 10%, you'll measure the lunar day at 33 hours, the solar day at 35.2 hours, and each local month will be 16 local days. Everything will reconcile, but you're still off by +10%. And I really don't see how the local plants and animals can give you any information about Earth time. | |

If you land on Mars then you are in luck, because everything lines up, and so being 5% or 10% early (18 and 36 respectively) early will account for the 37 minutes, or 9.3 days of drift. If the day feels longer or shorter, and by how much, you can do the same math and get the same rough "I should be X amount early" numbers. | |

Also the circadean rhythm might just adapt to that. Further, how does the observations on moons and terrain tell me anything useful? And the most important part, "From there, you can guess about how many Aliens days equal 365 Earth days" you didn't explain how can I heck guess that, which was exactly the purpose of the question. | |
