Getting the reporting site observation time

The observation time is the last time the data was updated. Some stations update every 2 seconds, so that might be why it looks like its only showing you the time when you check the data.

Thanks Brendan. That is probably the reason but I will have to check with the local site to see how often they update. From another API, I always assumed that the local info was only updated on the hour but that could easily be incorrect. I do know that the station is not staffed at 04:30 which was one of the times I checked and that was the time showing in observation_time. They probably use an automated system overnight and just staff the station during the day.
