Context

This event needs a creation time. Instead of inventing a string or integer convention, use protobuf's standard `Timestamp` message.

Task

Import google/protobuf/timestamp.proto and add a created_at field of type google.protobuf.Timestamp at tag number 2.

schema.proto

Valid Schema

syntax = "proto3";

package practice;

  string event_name = 1;
}
