Web/API/Window/mozAnimationStartTime

Non-standard This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Obsolete since Gecko 42 (Firefox 42 / Thunderbird 42 / SeaMonkey 2.39)This feature is obsolete.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.

Syntax

time = window.mozAnimationStartTime; 

Parameters

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