date.timestamp не найден в python?

После изменения импорта как from-import я столкнулся с этой ошибкой:

from datetime import datetime, date, timedelta
today = date.today()
from time import mktime
from feedparser import feedparser
import settings

def check_calendar():
    d = feedparser.parse(settings.personal_calendar_feed)
    for entry in d.entries:
        if(date.fromtimestamp(mktime(entry.date_parsed))==today):

Traceback (most recent call last):
  File computer.py", line 734, in <module>
    check_calendar()
  File "computer.py", line 210, in check_calendar
    if(date.fromtimestamp(mktime(entry.date_parsed))==today):
AttributeError: 'function' object has no attribute 'fromtimestamp'
