Different stop timetables in Matka.fi and Waltti in Turku

[PasiSalenius]

Asking for stop departure times in Turku at stop Kauppatori (T7) returns different results from /finland and /waltti endpoints.

The same query was done for both endpoints (used MATKA:T7 and FOLI:T7 as identifier):
stop(id: "FOLI:T7") { stoptimesForPatterns(startTime: "1504720472", timeRange: 7200, numberOfDepartures: 20) { ... } }

Snippet of result from Matka.fi
{ "pattern": { "code": "MATKA:7935249::01", "headsign": "Kauppatori", "directionId": -1, "route": { "gtfsId": "MATKA:7935249", "mode": "BUS", "shortName": "610", "longName": "Avanti-Kauppatori", "url": null } }, "stoptimes": [ { "trip": { "gtfsId": "MATKA:14_320414" }, "stop": { "gtfsId": "MATKA:T7" }, "scheduledArrival": 78480, "realtimeArrival": 78480, "scheduledDeparture": 78600, "realtimeDeparture": 78600, "serviceDay": 1504645200, "realtime": false }, { "trip": { "gtfsId": "MATKA:14_320415" }, "stop": { "gtfsId": "MATKA:T7" }, "scheduledArrival": 81960, "realtimeArrival": 81960, "scheduledDeparture": 82200, "realtimeDeparture": 82200, "serviceDay": 1504645200, "realtime": false } ] }

Also the other stoptimes have similar differences. Not all of them are explained by realtime updates.
