Obsolete. Returns a timestamp of the start time of the current refresh interval, such that multiple animations can be synchronized with each other.

Property of dom/Windowdom/Window


var result = element.animationStartTime;
element.animationStartTime = value;



Obsolete. Originally supported in pre-release versions of Internet Explorer 10, the animationStartTime property is superceded in favor of the property. Applications using animationStartTime should be updated accordingly. Use the animationStartTime property instead of recording animation start time using the function in order to ensure that the clock you are using has millisecond resolution and is monotonically increasing (where later values are always larger than earlier values). The value reported by the animationStartTime property represents the number of milliseconds between the recorded time and midnight January 1, 1970 (UTC).
