[Tagging] Public Transport Timetables Proposal RFC

Maybe we can put that optional piece of information inside the departures
key : departures=7:40,7:45 ; 8:40,8:45 -> means the train or the bus
arrives at the stop at 7:40 or 8:40 and leaves 5 minutes later.

Arrival and departure time are separated by a comma, and different
departures are separated by a semicolon.

If no comma, it means departure time only - except for the last stop :
means arrival time only.


Should we use 0-24-25 hour format ? (when a trip starts at 23:45 and
finishes 30 minutes later at 0:15, which is sometimes written 24:15 in a
gtfs. )
