title: Getting timestamp/creation date from Firebase doc, where it is not saved manually?
body: <p>Is it possible to get Timestamp or creation date from firestore doc? No matter how hacky the solution is, anything is viable. I believe firestore has to store some kind of timestamp to every object it saves? If so, is there any way to get to that value? Previously in beta v1, they had this create_time field, which is apparently now removed. Any help is greatly appreciated.</p>
  <p>Thank you.</p>
