Removing orphan status (25 April, 2018)
editI'm removing the orphan tag as I've created an appropriate link here from the larger "Timekeeping on Mars" article and have used the BROADER tag here to direct users there for more information.
Apparent vs. Mean
editIs a sol the apparent solar day (sundial time) or the mean solar day (clock time)? Since the article says a sol is 24 hours, 39 minutes and 35.244 seconds, I assume that it's clock time (because a sundial would give a different time every day). On the other hand, maybe NASA wants to keep track of the rovers by the position of the sun that a rover "sees" visually.
If no one objects, I'll go with my first impression and insert "mean" in the first paragraph. --RoyGoldsmith (talk) 00:36, 12 June 2018 (UTC)
A sundial on Earth would give a different time each day, because the planet does not rotate evenly. This does not preclude the possibility that Mars rotates evenly and thus solar measurements are even year-round. However, if the measurements are uneven, and the lengths are averaged over a Mars year, then I agree with your suggestion that the word "mean" would be appropriate.

Censorship

- @Legoines: It's not that you are not allowed, it's that Wikipedia is a collaborative project. You are welcome to propose changes by editing, but one editor can not decide on his own what should or should not be in an article. See for example this policy: WP:OWN. I do not think your changes improve the article, so I reverted them. You are now free to seek consensus for your changes by convincing other editors that the addition of a section on centi-sols would improve the article. To do that, you would probably need to show that reliable sources consider centi-sols to be relevant.
If you manage to convince other editors, I will have to concede, and the article would be changed. If you have any questions, you are very welcome to ask the teahouse help forum. The guide for new contributors might also be helpful, especially the part on discussion and consensus. Knuthove (talk) 16:49, 8 April 2021 (UTC)
