Hi Alex,

This is the joinExisting aggregation on time listed below?

I'm not sure if there is a way to configure the aggregation so the time 
coordinate is not converted to ISO string values. I'm guessing not but I will 
double check.

Can you send us some example datasets so we can look into why the time 
dimension is not the right size?

Ethan
