title: can I change timezone saved in Firestore timestamp field?
body: <p>so from the documentation in <a href="https://firebase.google.com/docs/reference/unity/struct/firebase/firestore/timestamp" rel="nofollow noreferrer">here</a> it said that</p>
  <blockquote>
  <p>A Timestamp represents a point in time independent of any time zone or
  calendar, represented as seconds and fractions of seconds at
  nanosecond resolution in UTC Epoch time</p>
  </blockquote>
  <p>but here is my timestamp field in my document</p>
  <p><a href="https://i.stack.imgur.com/i712I.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/i712I.png" alt="enter image description here" /></a></p>
  <p>as you can see, there is UTC+7. I am from Indonesia, and my Firestore database is also in region asia-southeast2 (Jakarta,Indonesia).</p>
  <p>my question is .....</p>
  <p>can I actually change that timezone ? even though the documentation says that timestamp is independent from any timezone. but I don't Understand why Firestore can get that UTC+7, which is correct because I send the data from Indonesia (UTC+7)</p>
  <p>I try to manipulate date object in my Android app, and send data using different timezone (UTC+9), but it will always be saved as UTC+7.</p>
  <p>so basically I am trying to find out if there is a bug in my code or timezone in firestore can't be changed</p>
