I have time data that was acquired in UTC format stored in memory as an array of doubles. I am plotting data in an XY graph with time as the x-axis and the X-scale formatted to be absolute time in UTC format. This is required to avoid shenanigans at daylight savings time boundaries. Unfortunately, I can not figure out any way to convince the graph that my time data is already in UTC format and it does not need to be automatically adjusted. I have tried subtracting off the UTC offset before sending the time data to the graph, and that works fine except for data that spans a DST boundary. Does anybody know how to handle data at the DST boundaries?
