Add a flag to control whether DocumentSnapshots return Dates or Timestamps for timestamp fields (#831)
* add a new property `timestampsInSnapshotsEnabled` to `FirestoreSettings`, `false` by default;
* add a verbose warning message urging users to opt into the new behavior;
* set `timestampsInSnapshotsEnabled` to true in the integration tests to reduce the verbose console
spam during the test run and make sure the flag won't break anything once it's flipped.

It can be passed to API + methods anywhere a system Date is currently accepted. To make + `DocumentSnapshot`s read timestamp fields back as `Timestamp`s instead of + Dates, you can set the newly added property `areTimestampsInSnapshotsEnabled` + in `FirestoreSettings` to `true`. Note that the current behavior + (`DocumentSnapshot`s returning system Dates) will be removed in a future + release. Using `Timestamp`s avoids rounding errors (system Date is stored as + a floating-point value, so the value read back from a `DocumentSnapshot` + might be slightly different from the value written). # v0.10.4 - [changed] If the SDK's attempt to connect to the Cloud Firestore backend |
