Add green energy feature for random within range jobs?

[physikerwelt]

The ~ operator allows scheduling a job randomly within a range. In #95, it is outlined how the operator works:

Instead of executing the job at random times, it might be better for the environment to execute it when green energy is available. This would require an API call to a program that determines if that is the case or not.

Is that something that could be imagined in the future? What would the requirements for the API be?

The current implementation is unfortunately not too helping with this RFE as the actual job execution time gets determined during the parsing of the crontab. So I am not sure how the API should look like.
