-## Reporting Timeline Range Progress: the ''getCurrentTime()'' method ## {#named-range-get-time}
-
-	Progress through named ranges is exposed on the {{AnimationTimeline}} object
-	by the {{AnimationTimeline/getCurrentTime()}} method:
-
-	<pre class="idl">
-		dictionary AnimationTimeOptions {
-		  DOMString? range;
-		};
-
-		[Exposed=Window]
-		partial interface AnimationTimeline {
-		  CSSNumericValue? getCurrentTime(optional AnimationTimeOptions options = {});
-		};
-	</pre>
-
-	<div class='methods'>
-	<dl>
-		<dt><dfn method for=AnimationTimeline lt='getCurrentTime()'>CSSNumericValue? getCurrentTime(optional AnimationCurrentTimeOptions = {})</dfn>
-		<dd>
-			Returns a representation of the [=timeline/current time=]
-			as follows:
-
-			<dl class="switch">
-				<dt>If {{AnimationTimeOptions/range}} is not provided:
-				<dd>
-					Returns the value of {{AnimationTimeline/currentTime}} on [=this=],
-					but representing millisecond values
-					as a new {{CSSUnitValue}} in ''ms'' units
-					rather than as a double.
-
-				<dt>If {{AnimationTimeOptions/range}} is provided
-					and is a valid [=named timeline range=] on [=this=]:
-				<dd>
-					Let |progress| be the current progress through that range,
-					expressed as a percentage value.
-
-					Create a [=new unit value=] from (|progress|, "percent")
-					and return it.
-
-					If the start and end points of the [=named timeline range=] coincide,
-					return negative infinity for time values earlier or equal to that point,
-					and positive infinity for time values after it.
-
-				<dt>
-					If {{AnimationTimeOptions/range}} is provided
-					but is not a valid [=named timeline range=] on [=this=]:
-				<dd>
-					Returns null.

-	ISSUE(8201): This method is related to {{AnimationTimeline/currentTime}}
-	but not quite the same; should it have a different name?
-
-	ISSUE: This method returns percentages relative to a ScrollTimeline’s range
-	when a range name is provided.
-	But for time-based timelines, if a range name is provided,
-	should it return percentage progress through that range,
-	or time progress through that range?

 # Appendix B: Timeline Name Scope # {#timeline-name-scope}
 
 	ISSUE: This section should move to CSS-ANIMATIONS-2.

 	Working Draft include:
 
 	* Removed <css>scroll-timeline-attachment</css> and <css>view-timeline-attachment</css> in favor of 'timeline-scope'.
 		(<a href="https://github.com/w3c/csswg-drafts/issues/7759">Issue 7759</a>)
 	* Switched named timelines to use <<dashed-ident>> instead of <<custom-ident>> in order to avoid name clashes with standard CSS keywords.
 		(<a href="https://github.com/w3c/csswg-drafts/issues/8746">Issue 8746</a>)
+	* Removed {{getCurrentTime()}} API due to various issues in the design.
+		(<a href="https://github.com/w3c/csswg-drafts/issues/8765">Issue 8765</a>)
+		Progress on an individual animation can now be retrieved using <code>Animation.progress</code>
+		(<a href="https://github.com/w3c/csswg-drafts/issues/8799">Issue 8799</a>)
+		and other use cases are deferred to Level 2.
