Binance order: Timestamp for this request was 1000ms ahead of the server's time
Question:
I am writing some Python code to create an order with the Binance API:
from binance.client import Client
client = Client(API_KEY, SECRET_KEY)
client.create_order(symbol='BTCUSDT',
recvWindow=59999, #The value can't be greater than 60K
side='BUY',
type='MARKET',
quantity = 0.004)
Unfortunately I get the following error message:
"BinanceAPIException: APIError(code=-1021): Timestamp for this request was 1000ms ahead of the server's time."
I already checked the difference (in miliseconds) between the Binance server time and my local time:
import time
import requests
import json
url = "https://api.binance.com/api/v1/time"
t = time.time()*1000
r = requests.get(url)
result = json.loads(r.content)
print(int(t)-result["serverTime"])
OUTPUT: 6997
It seems that the recvWindow of 60000 is still not sufficient (but it may not exceed 60K). I still get the same error.
Does anybody know how I can solve this issue?
Many thanks in advance!
Answers:
Manually set your clock back 1 second, ensure that ALL time updates are off. Daylights savings, autosync etc.
Probably the PC’s time is out of sync.
You can do it using Windows -> Setting-> Time & Language -> Date & Time -> ‘Sync Now’.
Screenshot:
Binance server time is behind your server time, because Binance servers do not sync often with ntp servers.
Workaround:
binance.setTimeOffset(-1000); // -1 sec
its if you use: npm binance
I actually used the accepted solution as it is desirable to have the correct windows time in any event.
Nevertheless, here is an alternative code solution (which makes a Binance class and computes the time offset) for the same:
import time
from binance.client import Client
class Binance:
def __init__(self, public_key = '', secret_key = '', sync = False):
self.time_offset = 0
self.b = Client(public_key, secret_key)
if sync:
self.time_offset = self._get_time_offset()
def _get_time_offset(self):
res = self.b.get_server_time()
return res['serverTime'] - int(time.time() * 1000)
def synced(self, fn_name, **args):
args['timestamp'] = int(time.time() - self.time_offset)
return getattr(self.b, fn_name)(**args)
and then call function like this:
binance = Binance(public_key = 'my_pub_key', secret_key = 'my_secret_key', sync=True)
binance.synced('order_market_buy', symbol='BNBBTC', quantity=10)

For C#, I created this method to run command line to resync time on windows before running an API on Binance
:
public static void ResyncWindowsTime()
{
var commands = new List<string>()
{
"net stop w32time",
"w32tm /unregister",
"w32tm /register",
"net start w32time",
"w32tm /resync"
};
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
process.StartInfo = startInfo;
foreach (var command in commands)
{
startInfo.Arguments = "/C " + command;
process.Start();
process.WaitForExit();
}
}
