seek to a point in html5 video

问题

Is it possible to seek to a particular point in html5 video displayed in a web page? I mean ,can I input a particular time value (say 01:20:30:045 ) and have the player control (slider) move to that point and play from that point onwards?

In older version of mozilla vlcplugin I think this is possible by seek(seconds,is_relative) method..but I would like to know if this is possible in html video.

Edit:

I created the page with video and added javascript as below.When I click on the link ,it displays the time of click..but it doesn't increment the play location..but continues to play normally.

Shouldn't the video play location get changed?

html

<video id="vid" width="640" height="360" controls>
       <source src="/myvid/test.mp4" type="video/mp4" /> 
</video>
<a id="gettime" href="#">time</a>
<p>
you clicked at:<span id="showtime"> </span> 
</p>

javascript

$(document).ready(function(){
    var player = $('#vid').get(0);
    $('#gettime').click(function(){
            if(player){
                current_time=player.currentTime;
                $('#showtime').html(current_time+" seconds");
                player.currentTime=current_time+10;
            }
        });
}
);

You can use v.currentTime = seconds; to seek to a given position.

Unfortunately it seems with some movie elements it behaves differently than others. For instance with an amazon video_element, it seems you must call pause before you can seek anywhere, then call play. However, if you call play "too quickly" after setting the currentTime then it won't stick. Odd.

Here is my current work around:

function seekToTime(ts) {
  // try and avoid pauses after seeking
  video_element.pause();
  video_element.currentTime = ts; // if this is far enough away from current, it implies a "play" call as well...oddly. I mean seriously that is junk.
    // however if it close enough, then we need to call play manually
    // some shenanigans to try and work around this:
    var timer = setInterval(function() {
        if (video_element.paused && video_element.readyState ==4 || !video_element.paused) {
            video_element.play();
            clearInterval(timer);
        }       
    }, 50);
}
