In order to synchronize your machine time with one of the internet time servers, you can write a Python client for that. For this, ntplib will be used. Here, the client/server conversation will be done using Network Time Protocol (NTP). If ntplib is not installed on your machine, you can get it from PyPI with the following command using pip or easy_install:

$ pip install ntplib
  

If pip is not installed on your computer, first install it before executing the preceding command. In Debian-based Linux distributions such as Ubuntu, this can be installed by:

$ sudo apt install python-pip
  

Note that you will need to install pip for Python 3 separately if you are running it along side Python 2, as typically Python 2 is set as the default version:

$ sudo apt-get install python3-pip
  

Similarly, ntplib needs to be installed for python3-pip (also called pip3) separately:

$ pip3 install ntplib  

It is a good idea to upgrade pip to the latest version if you are running an outdated version, by issuing the following command:

$ pip install --upgrade pip  

or:

$ pip3 install --upgrade pip  

If Python 2 and Python 3 are installed alongside in your computer then use pip3.

I am using the pip version 9.0.1, for both Python 2 and Python 3. This is the latest version at the time of writing.
