I'm trying to display timecode for the title currently playing.
I guess this can be implemented with the short period timer polling Player.Playlist.currentTitle.elapsedTime
and modifying Document.someInputTag.state.value accordingly.
But this looks like too complex solution. Are there more simple alternative approaches?
I have not found any among the samples.
P.S. I'm a newbie, so please excuse me if my questions are stupid.

I dont know any other solution than the one you described. I do this as part of my debug/building enviornment on a 1 second inteval.
Also if you look at Universal Studios titles, the tivo-esque widget when you fastforward/rewind is polling and displating in the same way.

Using a timer is probably the most straight forward approach. If you are using timers, I highly encourage you to take a look at this post: http://blogs.msdn.com/ptorr/archive/2007/08/29/using-timers-effectively-in-hdi.aspx
If you want to avoid timers, you could trigger the update by an event sent from a markup cue. Something like...
<timing clock="page">
<defs>
<g id="doTimeCheck">
<event name="checkTime"/>
<set style:width="201px"/>
</g>
</defs>
<par>
<cue select="id('elapsedTime')" begin="id('elapsedTime')[style:width()='200px']" dur="1s" use="doTimeCheck"/>
</par>
</timing>
<body>
<div style
osition="absolute" style:x="50px" style:y="50px" style:width="201px" style:height="100px">
<input mode="display" id="elapsedTime" style:font="font.ttf" style:fontSize="40px" style:width="200px" style:color="yellow" state:value="" />
</div>
</body>
and then listen for the event in the script:
addEventListener(
"checkTime", handleTimeCheck, false);function handleTimeCheck( evt )
{
var time = Player.playlist.currentTitle.elapsedTime;
evt.target.state.setProperty("value", time.substring(0,8));
}
with one of the two approaches described.
