I have tiltmeter data that I've entered offsets for (so to start at zero). The offset is being added twice on all charts with time span greater than 24 hours.
If I make a chart with 7 days, the offset it added twice. When I zoom in to the chart, I can see that the second addition of offset occurs at 18:00. My timezone is set to USA central (UTC - 6:00).......hmmmm
