Addendum to the 'Preventing the Python 3.12's "Deprecated since version 3.12: Use datetime.now() with UTC instead."' problem - with WARCIO 1.7.5 already published and giving us an option to avoid naive datetimes, it's prudent to use this option right now, as the changes on the previous commit for this problem will not use naive datetimes anymore, leading to potential conflicts on deltatimes until naive is removed for good from Python.
