last_changed_seconds wrong due to timezone

[sander1988]

I noticed that the last_changed_seconds property of an entity always is 7200 wrong. My timezone is +02:00 so this has to be a timezone issue.

It looks like 'now' isn't in UTC: https://github.com/AppDaemon/appdaemon/blob/4.2.1/appdaemon/entity.py#L575

I debugged the values during a state change trigger:

• last_changed property of entity: 2022-09-17T12:39:58.203138+00:00
• 'now' value at that time: 2022-09-17 12:39:58.219077+02:00 - There is no 'T' here, that's not a typo from my side.
• last_changed_seconds value: -7199.982804

I use this a current workaround, it might help someone fixing it:

    def _convert_to_seconds_ago(self, last_changed) -> float:
        utc = iso8601.parse_date(last_changed)
        now = datetime.datetime.now(datetime.timezone.utc)
        return (now - utc).total_seconds()
