After the clocks change due to Daylight Saving Time, you may see what looks like a gap in your data.
What in fact is happening is that the same hour is being repeated. So for example, 1 am to 1:59 am appears twice. See the scatterplot chart below which shows 1 am repeated.
So no data is actually "missing".
The reason for this is that our charting relies on JavaScript, and particularly in this case, the JavaScript Time objects. JavaScript in a browser does not support different time zones and looks at the machine's time. So if the machine's time changes due to daylight saving, a gap will appear in graphs with time intervals below an hour.
The time period we are looking at is when the daylight saving changes happened for Central Standard Time (CST). For the interval between 1:00 AM - 2:00 AM, we end up with double the number of runs. First interval (6 AM to 7 AM UTC) 2nd interval (7 AM to 8 AM UTC). In this case, the errors are happening in the first interval and depending on the timeframe that we are charting for, we might not include the data for both intervals.
For example, if you chart from 1:00-2:00 AM, you end up seeing no errors because we show data only for the second interval.
If you chart from 00:59 to 2:00 we would have to go back in time to include the data from the first interval and you end up seeing errors and additional runs.
