I presented what I consider to be a bug.  I opened an issue 9004, [1]
"datetime.utctimetuple() should not set tm_isdst flag to 0" for that.

There is no point in documenting the following as expected behavior:

>>> time.strftime('%c %z %Z', datetime.utcnow().utctimetuple())
'Wed Jun 16 03:26:26 2010 -0500 EST'

I believe it is better to fix it so that it produces

>>> time.strftime('%c %z %Z', datetime.utcnow().utctimetuple())
'Wed Jun 16 03:26:26 2010  '

instead.

This, however shows limitation of datetime to timetuple conversion:
there is currently no mechanism to store daylight saving time info in
datetime object.  See issue 9013. [2]  Rather than fixing that, it
would be much better to eliminate need for datetime to timetuple
conversion in the first place.
