Timestamp
A marker for a specific time inside a video, written as `1:23`. Clickable in comments and descriptions.
Written as `MM:SS` or `HH:MM:SS`, timestamps become clickable links when placed in comments or descriptions. The URL parameter `?t=90` (or `&t=90s`) does the same. SumTube's side panel renders chapter titles with a timestamp; clicking seeks the video directly.
