binance.exceptions.BinanceAPIException: APIError(code=-1021): Timestamp for this request was 1000ms ahead of the server's time

OS: Ubuntu 20.04 Python: v3.8.10 python-binance: v1.0.19

The same code worked fine, but after updating to the newest version, I am getting this issue repeatedly.

I checked if there's something wrong with My Server clock using this code :

from binance.client import Client
import time
import requests

for i in range(1, 10):
    local_time1 = int(time.time() * 1000)
    server_time = requests.get("https://fapi.binance.com/fapi/v1/time")
    diff1 = server_time.json()['serverTime'] - local_time1
    local_time2 = int(time.time() * 1000)
    diff2 = local_time2 - server_time.json()['serverTime']
    print("local1: %s server:%s local2: %s diff1:%s diff2:%s" % (local_time1, server_time.json()['serverTime'], local_time2, diff1, diff2))
    time.sleep(2)

I ran this above code at the time I was getting the errors on tmux

The code I am using

from binance import AsyncClient
import asyncio

async def binance_live(bot):

        await bot.futures_account_balance()

async def main():
        bot1 = await AsyncClient.create(xxx, xxx)
        bot2 = await AsyncClient.create(xxx, xxx)

        while True:
            loop.call_soon(asyncio.create_task,binance_live(bot1))
            loop.call_soon(asyncio.create_task,binance_live(bot2))
            await asyncio.sleep(10)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

binance.exceptions.BinanceAPIException: APIError(code=-1021): Timestamp for this request was 1000ms ahead of the server's time.         
Task exception was never retrieved.

I shouldn't get this issue if the time is synchronized, right? Mysteriously, the code works fine if I just rerun it.
