Orbital elevators and long, long days

I am inclined to think so (following Stephen Dole), but GURPS Space does not calculate daily temperature variation, and does not take any account of day length when calculating Habitability.

I have been doing a write-up of a planet that the starsystem generation sequence gave me as Affinity 8. Its days are 317.5 hours long. Which has no effect on the Habitability calculation--and neither does the temperature range induced by the absurd orbital eccentricity, nor the obliquity of 37°.
