Perspective Time-Series Chart time format

Quick question for you gurus here. I am using a time-series chart in perspective for one of my views. My data series for this chart is returned in user local time which I convert in a SQL query before building out the series, not UTC. I’m using the session prop for user timezone and the convert_tz function in the named query. I have noticed that the chart always offsets to UTC on the time axis. This worked fine in the XY chart and the times matched up perfectly. I decided to switch to the time-series chart because of the extra options for PanZoom. Am I missing something here with the time offset? Time format on the chart is h:m:ss and date format is M-D-YY
