Steps to Reproduce

Message.date is a datetime object created by PTB converting the original unix timestamp sent by telegram. It IS timezone aware, but uses UTC.

Expected behaviour

I fully expected that - because I've setup my local timezone using Default.tzinfo and passing it to ApplicationBuilder.defaults - the received Message.date would be localized in my local timezone.

Actual behaviour

This is not the case. AFAIK Default.tzinfo is only used to localize the datetime objects used for job_queue's jobs.
