[Tutor] Readable date arithmetic

I have the following method:

def get_log_dates(the_date_we_want_data_for):
  t = time.strptime(the_date_we_want_data_for, '%Y%m%d')
  t2 = datetime.datetime(*t[:-2])
  extra_day = datetime.timedelta(days=1)
  t3 = t2 + extra_day
  next_log_date = t3.strftime('%Y%m%d')
  return (the_date_we_want_data_for, next_log_date)

Quite apart from not much liking the t[123] variables, does date
arithmetic really need to be this gnarly?

How could I improve the above, especially from a readability
perspective?  Or is it ok?
