db.aggregate( [{ $documents: [ { mytimefield: new Date() } ] }, { $out: { db: "mydb", coll: "mycoll", timeseries: { timeField: "mytimefield" } } }, ]); db.getSiblingDB("mydb").mycoll.find()
^^ The above prints a single document with just the `mytimefield` field, no `_id`.
UPDATE: Apparently the _id on inserts comes from the driver.
