Appropriate logo for Support Notice

Daylight Saving Time (DST) for 2018 ends this coming Sunday, November 4th at 2:00 am. Clocks are turned back 1 hour. But, how should you account for that hour in your compliance reports?


Actually, EPA requires your DAS to remain on Standard Time for collecting and reporting data. See Part 75 Emissions Monitoring Policy Manual, Question 13.4 for more information.

How do you ensure your system remains on Standard Time?

Should the StackVision server be adjusted for daylight savings time?

Now, let's say November 4th came and went, and you realize that despite your efforts (or maybe because of your IT department's group policies), the time on your DAS did change. How do you correct that? Then this article in the ESC Customer Community is for you:
How do I correct the time on the StackVision server and data controller when the time has been changed due to Daylight Saving Time (DST)?
