Missing TZ in timestamp

[theOrakle]

Add module:

pip3 install python-dateutil

Simply added/modified the following to plantgw.py:

Added import: from dateutil.tz import tzlocal

Modified now() to include tzlocal(): MQTTAttributes.TIMESTAMP.value: datetime.now(tzlocal()).isoformat(),

data['timestamp'] = datetime.now(tzlocal()).strftime(self.config.mqtt_timestamp_format)

Thanks for this. The 2021.12 update officially broke all of my timestamp entities that didn't have a timezone, including Plant Gateway's. This helped me resolve manually. Would be nice to see something like this change enter the source.
