Connections travel back in time

[pietervdvn]

As mentioned earlier on slack, some connections travel back in time.

For example, in [https://graph.irail.be/sncb/connections?departureTime=2019-10-31T09:23:00.000Z], the connection with id http://irail.be/connections/8813003/20191031/S11981 seems to depart one minute before it arrived.

Note that this is probably related to incorrect delays.

As reference, the data I got from the server is copied below:
