Google Earth时间滑块步进/缩放分辨率不起作用?

我想增加时间滑块上的步进分辨率(缩放)。这可能吗?

在此博客中,看起来应该有可能,但我没有任何成功。 https://www.gearthblog.com/blog/archives/2016/11/animating-google-earth-part-3-time-toolbar.html

该图标已在我的Google地球专业版(v7.3.2)中启用,但单击后无任何作用。

Google Earth time slider

此功能是否有问题?

我将我的数据全天作为轨道(请参阅下面的示例,第一个和最后四个点),通常是10到14个小时的轨道,大约有20,000个坐标。默认分辨率增量对我来说太粗糙了。我希望滑块移动几秒钟而不是分钟,但是要做到这一点,我需要放大时间滑块(我猜是这样)。我理解正确吗?我的KML有问题吗?还是该功能按预期工作?

如果没有,是否有人知道最好的方法是什么(即在网页中)?

(仅供参考,以下KML示例中的多余名称空间引用是我在其中生成KML的SQL Server XML查询引擎的伪像。)
