get_ticker timestamps incorrect?

[john-robert]

Every 5 seconds I retrieve the ticker of HNT-USDT. It seems the times returned from the request are off and also jump back and forth. Here is the code:

import time
import datetime
from kucoin.client import Client

kucoin_client = Client('', '', '')

while True:

    start = time.time()      # now in seconds

    kucoin_ticker = kucoin_client.get_ticker('IOTA-USDT')
    kucoin_time = float(kucoin_ticker['time'])

    time_system = datetime.datetime.fromtimestamp( start )
    time_ticker = datetime.datetime.fromtimestamp( kucoin_ticker['time'] / 1000 )

    print(f'time of now: {time_system}')
    print(f'time ticker: {time_ticker}')
    print()

    # break condition
    wait = 5 - (time.time() - start)  # wait 5 seconds minus execution time of iteration
    time.sleep(wait)

The code results in an output like so:

time of now: 2022-01-07 09:50:20
time ticker : 2022-01-07 09:50:12

time of now: 2022-01-07 09:50:25
time ticker : 2022-01-07 09:50:12

time of now: 2022-01-07 09:50:30
time ticker : 2022-01-07 09:50:12

time of now: 2022-01-07 09:50:35
time ticker : 2022-01-07 09:50:32

time of now: 2022-01-07 09:50:40
time ticker : 2022-01-07 09:50:40

time of now: 2022-01-07 09:50:45
time ticker : 2022-01-07 09:50:35

The "time of now" behaves as expected (increasing by 5 s) but "time ticker" jumps back and forth for which I seeno explanation. For assets with high volatility (e.g. BTC, ETH) this problem does not occur. I therefore suspect it's related to the last price made, still that wouldn't explain why the ticker times can jump also backwards in time when it shouldn't (see last two ticker times). Any idea / explanation why this is observed? Thanks!
