Hi Alex,
You can set the lease expiration time when leasing the task, as in
the examples here:
http://code.google.com/appengine/docs/java/taskqueue/overview-pull.html#Leasing_Tasks
http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/taskqueue/Queue.html#leaseTasks(long,%20java.util.concurrent.TimeUnit,%20long)
I'm not aware of any built in way to set the lease time at task
insertion. To do that I'd use some configuration value with in your
app.
