title: Find out remaining time in Google Collab
body: <p>I am using <a href="https://colab.sandbox.google.com/notebooks/welcome.ipynb" rel="nofollow noreferrer">Google Collab</a> for some Machine Learning projects, mostly because of the free gpus it is offering and the nice setup.</p>
  
  <p>I know that every 12 hours, the environment is cleaned to prevent overusage.</p>
  
  <p>I would be interested to find a way to see how much time remains in order to save everything I would like to use in the future (e.g. model checkpoints) locally, before they get erased.</p>
  
  <p>Do you know any way to do that?</p>
  
  <p>Thanks for your time!</p>
