That other suggestion isn't good either. Let's say there is a train that leaves at a certain time. They will have to provide the exact GPS coordinates for someone to know when they need to be at the train station
That’s not as hard as it sounds. Google maps probably knows the exact location based on the name. Also, the user only needs to know the time at the station and the offset from local time e.g. “train leaves at 3 pm local, the time at the station is about 2 hours ahead of you now”.
