Background: I'm a North American operation running continental (12 h) shifts. As of March 9, we're running local Daylight Savings Time. Since March 10, I have Power BI reports summarizing each shift's production details going out twice a day at 8:30 (AM and PM) local DST using the Power BI Service "Subscriptions" feature; the timezones in this feature are labelled relative to UTC.
Problem: Suddenly, starting Sunday, March 30, these emails are showing up in our inboxes at 7:30. The only thing that has changed is that EUROPEAN Daylight Savings Time started Sunday, March 30 at 1:00 AM.
What's going on? Are the Timezones labelled as UTC but the Scheduled Time is actually relative to European Daylight Savings Time schedules?
