Refreshing NetworkLink by onExpire

[Xavi Arnaus]

Hi all.

I've done a simple kml to place in GE and to retrieve a list of items.
The intention is marking the list of items' kml to expire each day.
This way, the client only has a seed used to query the list and the
servers especifies when will the list be expired.

The client code is short:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1"
>
<NetworkLink>
<name>Some points</name>
<flyToView>1</flyToView>
<Link>
<href>http://local/prova.kml</href>
<refreshMode>onExpire</refreshMode>
</Link>
</NetworkLink>
</kml>

Let's say href is delivered from local at this time but will be online
and generated by the server.

The remote file, prova.kml, has an structure like this:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1">

<NetworkLinkControl>
<expires>2008-12-05T15:30:00</expires>
</NetworkLinkControl>

</kml>

When I add the client kml to GE, it calls the remote file and draws
the points. But it seems onExpire and exires tag is ignored, because I
change point's coordinates in server kml and never see the changes in
GE unless I manually click on uptade in GE.

I've verified the syntax with jedit (http://earth.google.com/outreach/
tutorial_jedit.html), activated Errors on GE (there're no errors), and
tried onInterval refresh mode as well with no luck.

I hope anyone can show me what I'm doing wrong.

Thank you all for your time.

Hi Xavi,

Have you double checked that your timezones are right? If you leave
off a timezone I believe that GE treats your KML time as UTC.
