      > db.createCollection("timeseries_123", { timeseries: { timeField: "a" } });
{ ok: 1 }

      Trying to change time-series collection validator with collMod command currently returns ok: 1 even though the change doesn't seem to be applied. An expected behavior would be to get an error similar to the view collection, something like "option not supported on a time-series collection: validator"
