title: Implement CreatedAt and UpdatedAt timestamp for DynamoDB Android SDK
body: <p>Need help with DynamoDB.</p>
  
  <p>I am switching back end from Parse.com (because they are retiring parse) to AWS mobile hub.</p>
  
  <p>I want to capture and save the date and time for which a row or item of data is written into my dynamodb table. In parse it is done automatically but not so in dynamodb.</p>
  
  <p>I have searched around on the internet for clues but no solid explanation or example at the moment.</p>
  
  <p>Can someone please point me in the right direction or pls show an example code here on how to implement CreatedAt and UpdatedAt into dynamodb.</p>
  
  <p>Do I get my system time and save it to dynamodb or get server time?</p>
  
  <p>If I need to get server timestamp which AWS server time do I get and how can I implement it?</p>
  
  <p>Thanks a lot.</p>
