如何在一天中的特定时间不协调地发送消息？

如何解决如何在一天中的特定时间不协调地发送消息？

我想做一个不和谐的机器人，每天在线课程开始时都会发短信给我。

import discord
from discord.ext import commands
from datetime import *
import discord.utils
from discord.utils import get
import pytz

local = datetime.Now()
tbilisi = pytz.timezone("Asia/Tbilisi")
datetime_tbilisi = datetime.Now(tbilisi)


Monday = "Monday"
dro1_saati = 9
dro1_wuti = 30

async def on_ready():
    channel = discord.utils.get(client.guilds[0].channels,name = "general")
    await client.change_presence(status = discord.Status.online,activity = discord.Game("with z.help_me | Aleksandre"))
    #Monday
    if Monday == datetime_tbilisi.strftime("%A") and dro1_saati == datetime_tbilisi.hour and dro1_wuti == datetime_tbilisi.minute:
        embed = discord.Embed(title = "Monday",description = ": https://us04web.zoom.us/j/78382716896?pwd=RUxiZExKRHFadSszS01pZWk0WVNKQT09k\n ID:783 8271 6886 \n Pass:1010",colour = discord.Colour.blue())
        await channel.send(embed = embed)

当我在Heroku上托管它时，它不起作用。
