// Specification of the Firestore API.

// The Cloud Firestore service.
//
// This service exposes several types of comparable timestamps:
//
// *    `create_time` - The time at which a document was created. Changes only
//      when a document is deleted, then re-created. Increases in a strict
//       monotonic fashion.
// *    `update_time` - The time at which a document was last updated. Changes
//      every time a document is modified. Does not change when a write results
//      in no modifications. Increases in a strict monotonic fashion.
// *    `read_time` - The time at which a particular state was observed. Used
//      to denote a consistent snapshot of the database or the time at which a
//      Document was observed to not exist.
// *    `commit_time` - The time at which the writes in a transaction were
//      committed. Any read with an equal or greater `read_time` is guaranteed
//      to see the effects of the transaction.
