title: Get current server Date and Time in Firebase Firestore
body: <p>I want to get my server time in Firebase Firestore so I can use it for my countdown logic. I can't find anywhere and mostly they suggest to use <code>FiedValue.serverTimeStamp</code> or <code>ServerValue.TIMESTAMP</code> which is both are used to save data. I don't want to save data I just want to get the server time.</p>
  
  <p>Is there a static way like <code>FirebaseFirestore.getInstance().getServerTime()</code>?</p>
