How to Mock a TLS Certificate Rotation Schedule in Python

import datetime
import random
import time

        self.cert_name = cert_name

        self.last_rotated = datetime.date.today() - datetime.timedelta(days=random.randint(10, 25))
        self.next_rotation = self.last_rotated + datetime.timedelta(days=self.rotation_days)

            return True
        return False

    def status(self):
