Why use a timer, what about storing time in a "taken_time" column in your model, then subtract expiration time from current and check if this number is grater than the "Taken time" timestamp
In the view the gets ready to render a browsable object, just do the same time difference hickamajig as above and determine if the item is available before rendering it to the template? I think you can also do the math in the template... my preference is to keep as much logic as possible out of the presentation layer.
