Summary0002943: Wrong Moon Rise and Set Times in Ephemeris, and Details
DescriptionWhen checking the rise/set times in the Ephemeris Calendar, they are totally wrong when compared to rise/set times from other sources.

For example: https://www.timeanddate.com/moon/canada/toronto

The same error can be found when clicking on the moon, and selecting the object details, at the very bottom:

Rise: Local horizon 03h42m42s Azimuth: [...]
Transit: [...]
Set: Local horizon 14h06m33s Azimuth: [...]

Steps To Reproduce- Set location to Toronto, Ontario, Canada.
- Change the timezone to America/Toronto
- Search for "moon"
- Click on the moon in the sky chart
- Click on the "Moon" label that pops up
- Scroll to the bottom, to see the local horizon rise and set

Also:

- Click on Ephemeris button
- Select Solar System, then Moon

Compare the rise/set to the link here:

https://www.timeanddate.com/moon/canada/toronto

Then advance the time to the correct rise/set from the above web page
Then mouse over the moon, and check the rise/set at the very bottom

Please ignore the above report.

The reason the rise and set were inaccurate is because I have a local horizon line, including trees and buildings.
And there is a setting under the Horizon tab saying : "Compute rise/set time relative to this line".
Once I unchecked that setting, the rise and set times are back to the normal ones.

Maybe this issue will be useful for someone who is confused because of a local horizon line.

Good you find it.

This is not an issue but a feature, if you want to observe the moon it need to be above the trees.
The mention "Local horizon" is to indicate that.
Maybe this is more clear if I can change it to "Local profile".
