Arc GIS 10 includes support for time-aware layers, which store information about the changing state of a dataset over time.
Time-aware layers allow you to step through periods of time revealing patterns and trends in your data.
The main directory is set to "Expire Immediately" via IIS's properties dialog.
That means "keep it fresh." Underneath the main directory is a directory called /js that is set to expire in 7 days, as seen at right.
There are several ways to work with time-aware layers in a Web API based application.
The simplest is to use the Time Slider widget because it handles the process of updating the map's time extent for you.
A visitor is someone who goes to your site but does not use the messenger.You should be setting the extent of the time slider and setting the position of the time thumb(s), which then updates the current time extent of the map.If you have already configured your time slider, this is as simple as: This will move the time slider's thumb position to the first time stop, which will then update the map's time extent to match.Alternatively, you can use the Web APIs to build applications that perform temporal queries, filter layers using time definitions, and set the map's time extent.You can make your layers time-aware using the Layer Properties dialog in Arc Map(right-click on the layer in Arc Map and choose Properties to display the dialog). The time information is preserved and accessible through the map service when you publish your map to Arc GIS Server.
