Python-3.12: do not use datetime.datetime.utcnow()

Browse Source 
This is deprecated in the favor of:
  datetime.datetime.now(datetime.timezone.utc)

In order to return a ``datetime.datetime`` object without the TZ
zone defined, the ``tzinfo`` member is deleted. That allows the
addition/substraction from offset-naive ``datetime.datetime`` objects.
