public virtual double RawTime { get; set; }

Setting this value actually calls UnityEngine.Playables.PlayableExtensions.SetTime``1(``0,System.Double) twice to ensure that animation events aren't triggered incorrectly. Calling it only once would trigger any animation events between the previous time and the new time. So if an animation plays to the end and you set the time back to 0 (such as by calling Animancer.AnimancerState.Stop or playing a different animation), the next time that animation played it would immediately trigger all of its events, then play through and trigger them normally as well.
