Eastern Time. The chart below should update, but at most once every hour 20 minutes, and there is at most one data point for every minute. For now, the chart only updates when I am moving, so data for an hour of the day after which I am not awake will likely be delayed until the morning. I'll N/A if there are sufficiently severe bugs, particularly if steps are missing because something broke. I have a redundancy that isn't connected to the chart and will resolve based on that if that does not break, but I hope that doesn't need to happen. My phone running out of battery for a substantial amount of time is the only single point of failure for the market, I think. (I'll also test it tomorrow.)

I won't bet.
