Time shift problem publishing SolCast forecast in JSON

I wrote a python script

Of course the timestamp of the SolCast JSON is in UTC, with the Z at the end.

Beware, Python treats a timestamp with a Z in it as local time not UTC.

Treating of time in Emoncms - UTC or BST

Not processing Z might still be a bug is a feature Issue 35829: datetime: parse "Z" timezone suffix in fromisoformat() - Python tracker. You need to test it yourself. Potentially simply replace the Z for +00:00 in the string first. [edit] datetime.fromisoformat(my_date.replace('Z', '+00:00')) [edit Nov 2023] It occurs to me this will create erroneous results if DST is in effect. I think the Z should just be removed so the time is assumed to be local time when converted.
