“Offline” status

Due to power or weather conditions, the weather stations frequently go offline or fail to report data for a long period of time. I was in the LZ a couple of weeks ago, and several pilots were talking about the current conditions that the Marshall station was reporting. I had to let them know that the data was over an hour old, as it wasn’t obvious on the charts that that was the case.

I put a check in the new graphs (and the compass gauges) to show an “Offline” message if the last data received is over an hour old. I think this is too long still, but wanted to start with low impact first.

Should this timeframe be lowered, and how much?
