The settings for date and time are causing us (our organisation), problems when we transition between UTC (Zulu) and Daylight Savings Time (DST). Workflows that are time dependent go from working normally, to being one hour out - transitioning either way around.

Our NAC regional settings are set to this: (UTC/UTC+01:00) Europe/London

Workflows are set to use the tenant default, is that correct, or should it be just plain UTC coordinated universal time?

My understanding of (UTC/UTC+01:00) Europe/London is both UTC + 00:00 winter and UTC + 01:00 summer. I also regard that as meaning that the time with change in accordance with DST.

What I need to understand is how to make the NAC and any workflows running in it, follow time changes throughout the year. Please can anyone provide some guidance?
