Steps to reproduce: 1. Set simulation rate to "2 mins" in the toolbar. 2. Look at the on-screen label "LT: ...". The actual rate is about 1 hour per second which is 30x faster than the requested 2 minutes per second. KStars version: 2.7.2 (16.12.3-2.fc26)
It's fixed in GIT now. Interesting solving this bug also resolved another decade old bug as well, completely unrelated to this.
Now when rate is set to 2 mins (or faster) rendering only happens once per 1 second. It is less usable than it was because now it's hard to follow a particular star with you eye.
Yes I tried to implement better time resolution for 2 min+ but it didn't work out well since a lot of calculation slow the process down. If you have a better solution, please submit a patch!
