Other users have experienced this problem and it appears it has to do with Zulu time offsets. This has been frustrating for me also. I just changed my light schedule using the -5.00 ZULU offset for Florida Eastern Time. Hoperfully, this resolves my problem as well. Is Ring going to update the app to guide users to use Zulu time instead local time on light schedule? Or, reconfigure the app to add time zone selections for the Zulu offsets like marine GPS units use?
