Yeah... there is more related weirdness going on.

>>> datetime(1970, 1, 3).astimezone(timezone.utc)
datetime.datetime(1970, 1, 2, 16, 0, tzinfo=datetime.timezone.utc)
>>> datetime(1970, 1, 2).astimezone(timezone.utc)
Traceback (most recent call last):
  File "", line 1, in 
OSError: [Errno 22] Invalid argument
>>> datetime(1970, 1, 1, 16, 0, tzinfo=timezone.utc)
datetime.datetime(1970, 1, 1, 16, 0, tzinfo=datetime.timezone.utc)

[issue31116] base85 z85 variant encoding

[Dobatymo]

Dobatymo  added the comment:

base64.b85encode does not use ", ' or \ as well.

That's the _b85alphabet 

_b85alphabet = (b"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
b"abcdefghijklmnopqrstuvwxyz!#$%&()*+-;<=>?@^_`{|}~")

Sorry, I forgot about the bit alignment when I was checking for the footer. 
This can be closed then.

[issue37005] bz2 module doesn't write end-of-stream marker

[Dobatymo]

New submission from Dobatymo :

According to https://en.wikipedia.org/wiki/Bzip2 the reference implementation 
of bzip2 writes an end-of-stream marker (also called stream footer) with a 
magic number and a stream checksum to the file.

Python does not do so. The files can still be read by all bzip2 compatible 
software I tried. For completeness and better error detection however, writing 
this marker (optionally maybe) would be useful.
