wrong arrival and departure times in planBZ decoder

[MichaelKreil]

Sometimes the arrival and departure times are bigger than 1440 (number of minutes per day). There seems to be a difference of exactly 2048. Obviously a time (0-1439) can be represented by 11 bits, but currently 12 bits are extracted in the decoder.

I am aware of that, but I have not been able to figure out what this flag means. I suspected different timezones or multiple stops of the same train at the same station, but this does not fit.
