Find a way to sync system time

This script can do it but needs elevated privileges:
```python
import time
import os

try:
    import ntplib
    client = ntplib.NTPClient()
    response = client.request('pool.ntp.org')
    os.system('date ' + time.strftime('%m%d%H%M%Y.%S',time.localtime(response.tx_time)))
except:
    print('Could not sync with time server.')

print('Done.')
```
