Hello I have a script that does a GET request and I need to measure the thread that is loaded with that function. This is the code that I have written but it doesn`t show the correct time it shows 0 and sometimes 0.001 or something like that.

```
import requests
import threading
import time

def functie():
    URL = "http://10.250.100.170:9082/SPVWS2/rest/listaMesaje"
    r = requests.get(url = URL)
    data = r.json()

threads = []
for i in range(5):
    start = time.clock_gettime_ns()
    t = threading.Thread(target=functie)
    threads.append(t)
    t.start()
    end = time.clock_gettime_ns()
    print(end-start)

```

I need an example on how to get in my code the exact thread execution time. Thanks
