Hi all! First post here, so I’m excited to get some feedback!
For context, I do a report on our organization’s EV chargers every month. In this report, I need to calculate the average time of day people are charging, the average charge time (duration), and the total duration.
Currently, I am unable to get the average duration and the total duration.
Here’s my process
- Convert the time to FME format using a DateTimeConverter
- Sum and average the times using a SatisticsCaclulator
- I attempt to convert the summary back into H:MM...

But then I am met with the below error:

Where am I going wrong?
