problems with removing czml

Then the object is not rendering,but the clock animation is still tracking as loop. How can I stop the loop,and set the clock as the current time.

Could you help me?

Hi, I remove the czml object with DataSoureceCollection.removeAll().

If you want to track the system clock, set

clock.clockRange = Cesium.ClockRange.UNBOUNDED;

clock.clockStep = Cesium.ClockStep.SYSTEM_CLOCK_MULTIPLIER;
