1.Calculate the total time using sum aggs.  
2. Calculate the number of users using cardinality aggs.  
3. Count the total time/number of users using a bucket script to get the average time.

However, if the total time is 0 or the number of users is 0, bucket script results are not provided.  
How can I set it to 0 if there is no current value?
