@tasks.loop() didn’t work.

Hello I want to write some task that fires daily about specific hour. I copy and paste example code from discord.py documentation but it didn’t work. No errors, no warnings just nothing. I set up all intents and administrator permision on my bot. Ofcourse I’ve changed time parameters to few minutes after my current time.

import datetime
from discord.ext import commands, tasks
from config import TEST_SERVER
import pytz

utc = pytz.UTC

time = datetime.time(hour=10, minute=35, tzinfo=utc) 


class MyCog(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.my_task.start()

    def cog_unload(self):
        self.my_task.cancel()

    @tasks.loop(time = time)
    async def my_task(self):
        print("My task is running!")

    @commands.command()
    async def test_ping(self, ctx):
        await ctx.send("Test ping")

async def setup(bot:commands.Bot) -> None:
    await bot.add_cog(MyCog(bot), guild=TEST_SERVER)

I’ve only added test ping command which works, setup and pytz for timezone aware.
Someone know why what’s going on?
