[SOLVED] Double hourly notification Python, Ubuntu, Telegram

Issue

When developing the telegram bot in python, I faced the problem of independently triggering notifications in the Ubuntu system. Let's start from the beginning. For everyday notification, I use a library called "Schedule". I won't fully describe it in the code, but it looks something like this:

from multiprocessing import *
import schedule

def start_process():
   Process(target=P_schedule.start_schedule, args=()).start()

class P_schedule():
   def start_schedule():
       schedule.every().day.at("19:00").do(P_schedule.send_message)

   while True:
       schedule.run_pending()
       time.sleep(1)

   def send_message():
       bot.send_message(user_ID, 'Message Text')

There don't seem to be any errors here for correct operation. Then I loaded all this into the Ubuntu system and connected "systemd" to autorun with commands:

vim /etc/systemd/system/bot.service

[Unit]
Description=Awesome Bot
After=syslog.target
After=network.target

[Service]
Type=simple
User=bot
WorkingDirectory=/home/bot/tgbot
ExecStart=/usr/bin/python3 /home/bot/tgbot/bot.py
Restart=always

[Install]
WantedBy=multi-user.target

systemctl daemon-reload
systemctl enable bot
systemctl start bot

I restart "systemd" after making edits to the code with a command:

systemctl restart bot

The problem arose in the following, when I change the time of the notification, it starts coming at the time that I specified and at the time that was before, as I understand it, "systemd" somewhere in the cache stores the old time value. How can I update "systemd" to clear this very cache.

Solution

It helped to reboot the system with the command:

sudo systemctl reboot
