My goal is to output the current time every 10 seconds but for some reason the value does not update and it only prints the original time.

```
def runTest():

    current_time = now.strftime("%H:%M:%S")
    print(current_time)
    time.sleep(10)
    runTest()

```

output:

```
18:25:08
18:25:08
18:25:08

```
