非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

Obsolete since Gecko 42 (Firefox 42 / Thunderbird 42 / SeaMonkey 2.39)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Returns the time, in milliseconds since the epoch, at which animations started now should be considered to have started. This value should be used instead of, for example, Date.now() , because this value will be the same for all animations started in this window during this refresh interval, allowing them to remain in sync with one another.

This also allows JavaScript-based animations to remain synchronized with CSS transitions and SMIL animations triggered during the same refresh interval.

句法

time = window.mozAnimationStartTime;

参数

time is the time in milliseconds since the epoch at which animations for the current window should be considered to have started.
