Hi there Mike,
I wanted to thank you for reaching out to us about the ATA not updating with the time change. I was able to confirm that our devices do not have the ability to update via the time change automatically unfortunately, and that at this time it does require a powercycle of the ATA to make sure the time setting updates. Since this might change in the future with new equipment or software updates, I have noted your account so that if something does change we will reach out to you and keep you updated.
Thank you again for posting about this issue, and I hope you reach out again if anything comes up in the future!
