I'm fetching quotes values by using Websocket, with two different code and getting different values.

My first Code is -

from kiteconnect import KiteConnect
import time
from kiteconnect import KiteTicker

kws = KiteTicker(zerodha_api_key,acc_tkn)

tokens = instrument_token       #[instrumet_token List] 

def conditions(ticks):
    dataframes = []
    for i in range(len(ticks)):
        instrumnet_token = ticks[i]['instrument_token']
        if instrumnet_token in tokens:
            index_number = tokens.index(instrumnet_token)
            strike_price = strike[index_number] 
            
            datetime = ticks[i]['exchange_timestamp']
            bid_price = ticks[i]['depth']['buy'][0]['price']
            ask_price = ticks[i]['depth']['sell'][0]['price']
            
            print(instrumnet_token, " ", strike_price, " ", datetime, " ", bid_price, " ", ask_price)
            
            output_df = pd.DataFrame(columns = ['Instrument_token', 'Strike', 'Datetime', 'Bid_price', 'Ask_price'])
            c = 0
            output_df.loc[c] = [instrumnet_token, strike_price, datetime, bid_price, ask_price]
            dataframes.append(output_df)
        else:
            pass
        print("-------------------------------------------------")
    df = pd.concat(dataframes)
    display(df)
    print("\n\n")
        
        
def on_ticks(ws, ticks):
    ticks = (ticks)
    conditions(ticks)
         
def on_connect(ws, response):
    ws.subscribe(tokens)
    ws.set_mode(ws.MODE_FULL,tokens)


kws.on_ticks = on_ticks
kws.on_connect = on_connect
kws.connect(threaded=True)
count=0
while True:
    count+=1
    if(count%2==0):
        if kws.is_connected():
            kws.set_mode(kws.MODE_FULL,tokens)
        else:
            if kws.is_connected():
                kws.set_mode(kws.MODE_FULL,tokens)
        time.sleep(1)

and Getting back to back output -


and my second code is this -

logging.basicConfig(level=logging.DEBUG)

kws = KiteTicker(zerodha_api_key,acc_tkn)

tokens = instrument_token
print(tokens)
print(strike)

def on_ticks(ws, ticks):
    logging.debug("Ticks: {}".format(ticks))

def on_connect(ws, response):
    ws.subscribe(tokens)
    ws.set_mode(ws.MODE_FULL, tokens)

def on_close(ws, code, reason): 
    ws.stop()

kws.on_ticks = on_ticks
kws.on_connect = on_connect
kws.on_close = on_close
kws.connect(threaded=True)

while True:
   #Perform required data operation using tick data
    def on_ticks(ws, ticks):
#         print(ticks, "\n\n\n")
        helper_method(ticks)

    def helper_method(ticks):
        dataframes = []
        for i in range(len(ticks)):
            instrumnet_token = ticks[i]['instrument_token']
            if instrumnet_token in tokens:
                index_number = tokens.index(instrumnet_token)
                strike_price = strike[index_number] 

                datetime = ticks[i]['exchange_timestamp']
                bid_price = ticks[i]['depth']['buy'][0]['price']
                ask_price = ticks[i]['depth']['sell'][0]['price']

#                 print(instrumnet_token, " ", strike_price, " ", datetime, " ", bid_price, " ", ask_price)

                output_df = pd.DataFrame(columns = ['Instrument_token', 'Strike', 'Datetime', 'Bid_price', 'Ask_price'])
                c = 0
                output_df.loc[c] = [instrumnet_token, strike_price, datetime, bid_price, ask_price]
                dataframes.append(output_df)
            else:
                pass
#             print("-------------------------------------------------")
        df = pd.concat(dataframes)
        display(df)
        print("-------------------------------------------------")
        print("\n\n")

    #Assign callback
    kws.on_ticks=on_ticks
   

and I'm getting output this -


So I want to know why both values have different Datetime?

A possible reason could be because of blocking of one ticker thread, adding a slight delay in ticker data consumption. You should try out the solution mentioned in your similar raised thread here.
