Here's an example of using a popup with a dynamic map service:

JSFiddle: http://jsfiddle.net/swingley/Bkswj/This sample is using a query task to get features that intersect a click point and then using the deferred returned by the query task to set features for the map's popup.If you're underlying data is time-enabled, use a timeExtent property on your query to query by time.
