This was added in Level 2 of the Web Animations spec In this level of the spec, all time values associated with animations (including this duration property) are no longer simple numbers but are instead either percentages or numbers for progress- and time-based timelines respectively. These values are represented internally by a new `TimeValue` wrapper struct, and externally (i.e. in JS) as `CSSNumberish`.
