How to Add a Timestamp on a YouTube Comment

Timestamps in YouTube comments are one of those small features that completely change how people interact with video content. Whether you're pointing a friend to the best moment in a three-hour livestream or flagging a specific tutorial step, a clickable timestamp turns a vague reference into a direct link. Here's exactly how it works — and what affects whether it behaves the way you expect.

What a YouTube Comment Timestamp Actually Does

When you type a time value in a specific format inside a YouTube comment, YouTube automatically converts it into a clickable hyperlink. Anyone who clicks that link gets taken directly to that moment in the video — no scrubbing required.

This isn't a special mode or a hidden feature. It's built into YouTube's comment system and works on both desktop and mobile, across browsers and the YouTube app.

How to Type a Timestamp in a YouTube Comment

The format is straightforward:

  • 0:00 — minutes and seconds (works for videos under one hour)
  • 0:00:00 — hours, minutes, and seconds (works for longer videos)

Step-by-Step on Desktop

  1. Open the YouTube video you want to comment on
  2. Click into the comment box below the video
  3. Type your comment, then include the timestamp in the correct format — for example: "The explanation at 14:32 is really clear"
  4. Post the comment

YouTube will automatically detect the time format and render it as a blue, clickable link.

Step-by-Step on Mobile (iOS or Android)

  1. Open the YouTube app and navigate to the video
  2. Tap the comment icon or scroll to the comments section
  3. Tap Add a comment...
  4. Type your comment with the timestamp included in the same format
  5. Tap the Post button

The timestamp will appear as a hyperlink once the comment is published — it won't look clickable while you're typing, but it activates after posting.

Getting the Time Right ⏱️

The most common issue isn't the format — it's finding the exact moment you want to reference. A few ways to nail it:

  • On desktop: Hover your cursor over the progress bar to see the timestamp preview, or check the time counter in the bottom-left of the player
  • On mobile: Tap the video to bring up the controls, then drag the scrubber — the current time displays as you move it
  • Right-click shortcut (desktop): Right-click anywhere on the video and select "Copy video URL at current time" — this copies a shareable link with the timestamp embedded, which you can reference when writing your comment

What Affects Whether Timestamps Work

Not every timestamp you type will behave identically. A few variables matter:

The Video's Length and Structure

Timestamps only link to valid points within the video. If you type 1:22:45 on a 45-minute video, the link will still appear, but clicking it may just load the end of the video or behave unexpectedly. Always confirm the time exists within the actual video duration.

Whether the Video Allows Comments

Creators can disable comments entirely. If comments are turned off, you won't be able to post a timestamp — or any comment — regardless of what you type.

Livestreams vs. Uploaded Videos

Behavior varies here. On standard uploaded videos, timestamps work reliably. On active livestreams, timestamp linking is inconsistent because the video length is constantly changing. Once a livestream is archived and processed as a regular video, timestamps in comments tend to work more predictably.

App Version and Platform

Older versions of the YouTube app occasionally render timestamps as plain text rather than hyperlinks. If your timestamp isn't becoming clickable, checking for an app update is worth doing before assuming something else is wrong.

One Thing That Catches People Off 🎯

YouTube does not support timestamp linking from external comments — meaning if you paste a timestamp-formatted text into a social media post, email, or forum thread, it won't automatically link to that moment in the video. Clickable timestamps are a YouTube comment system feature specifically. To share a timestamped link externally, you'll want to use the Share button on the video, enable the "Start at" option, and copy that URL instead.

When the Format Looks Right but Still Doesn't Work

If you've typed the format correctly and the timestamp still appears as plain text after posting, consider:

  • Browser extensions that modify YouTube's interface can interfere with comment rendering
  • Comment editing — if you edit a comment after posting, YouTube occasionally re-processes it, and sometimes timestamps need a page refresh to display correctly
  • Region or account restrictions — in rare cases, restricted mode or account-level settings can affect comment feature availability

The core mechanism is consistent, but the surrounding ecosystem — your device, the video type, your account settings, and the creator's own configuration — shapes exactly what you'll experience when you put it into practice.
