/**
 * 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.
