No timestamps in KML file?

[routeconverter]

Eh? Of course KML files support timestamps! Here's an example.
[..]

We're getting closer and closer. The example uses <Placemark> and a new KML Extension introduced with Google Earth 5:

<gx:Track>
<when>2010-05-30T08:10:40Z</when>
<when>2010-05-30T08:42:58Z</when>
<when>2010-05-30T08:43:37Z</when>
[...]
<gx:coord>-1.514117 50.669709 11</gx:coord>
<gx:coord>-1.513529 50.66998499999999 9.000000000000002</gx:coord>
<gx:coord>-1.513229 50.67039199999999 11</gx:coord>

Note, that this is a Google-specific extension to KML 2.2 and currently RouteConverter only reads this structure and displays it as a Track. Feel free to extend the code and submit a merge request.
