As far as I can see, every time something changes on datetime.strptime(), it will invalidate that section of the documentation. On the other hand, I believe the comparison with datetime(*(time.strptime(date_string, format)[0:6])" is interesting and valuable to keep.
Given that, instead of "This is equivalent to [...]", I would suggest something like:
"This is similar to [...], but datetime.strptime() is better since it retains both microseconds and timezone data."
