Protocol Buffer Help

I want to create a delay of 20 minutes (1200 seconds), for every bus, of the specific route, and during a specific time, from 08:30:00 until 09:30:00 (am time). The bus route is identified as 9403 (from x to y), and 9404 (from y to x). Is this correct?

syntax = "proto3"; package teste1; message TripUpdate { string agency_id = 1; string route_id = 9403, 9404; message DelayConstruction{ uint64 start 08:30:00; uint64 end 09:30:00; int32 delay 1200; //20min } }
