With Embedded YouTube Video, Create Link that Jumps to Specific Time

Question

On Wordpress, I'm trying to embed a YouTube video, then include links that jump to specific times in that video. So if I want to jump to 2:00, I can create a link that jumps to that point in the embedded video.

I found a similar question from a few years ago, but I believe the YouTube API has changed. I cannot find any plugins that can do this, so want to do it on my own if possible.

Suggestions?

Edit: Here is the code I've come up with so far. However, the only issue is that if the video hasn't been played yet, then seekTo seems to take a long time. I'm not sure if I should response to the onReady event, or another.

add_action( 'wp_enqueue_scripts', 'register_yt_frameapi' );

function register_yt_frameapi() {
    wp_register_script( 'frameapi', 'https://www.youtube.com/iframe_api', array(), '1.0.0', true );
}

add_shortcode('ytlink', 'ytlink');
function ytlink($atts, $content = null)
{
    wp_enqueue_script('frameapi');

    $id = $atts['id'];
    $time = $atts['time'];
    $timeParts = explode(':', $time);
    $seconds = 0;
    for ($i = 0; count($timeParts); $i++)
    {
        $seconds += array_pop($timeParts) * 60 * $i;
    }

    return '<a href="javascript:void(0);" ' .
    'onclick="var player = new YT.Player(\''.$id.'\', {events: {onReady: function () {player.seekTo('.$seconds.', true);}}});">'.
    ($content ?? $time) . '</a>';
}

Okay, I got this figured out finally. I'll post my solution here in case anyone else has the same question. I don't know if there may be a better way to do this, but this is the best I found.

Javascript:

var player;
var ytSeconds = 0;

jQuery(document).ready(function ()
    {
    player = new YT.Player('yt-embed', {events: {
      'onStateChange': onPlayerStateChange
      }
      });
    });

function onPlayerStateChange(e)
{
  if (e.data == 1 && ytSeconds > 0) {
    e.target.seekTo(ytSeconds);
    ytSeconds = 0;
  }
}

function seekTo(seconds)
{
  if (player.getPlayerState() == 1) {
    player.seekTo(seconds);
  }
  else {
    ytSeconds = seconds;
    player.playVideo();
  }
}

Then links just look like:

<a href="#" onclick="seekTo(120);">02:00</a>
