Shodows analysis

1. A concise explanation of the problem you’re experiencing.

I am doing shadow analysis for Lod1 and Lod2 buildings. Could there be a harmony problem between the clock and the sun? 17/December/2017 hour 06:00 => this date is born in Istanbul at 8:00 am in the sunshine.This is the correct one.

But cesium is at 6 o’clock the sun is already born.

**Is there any explanation about this ? **How can I fix ?

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you’re using, your operating system and browser.

Cesium version 1,39

It seems to be correct when I compare it with the New York tileset. The Cesium clock is in UTC whereas Istanbul is 3 hours ahead of that. In that screenshot you are really looking at 9:04 am local time.
