I have perspective table used for tag history data.
I want to show tag data history of each day at 00:00:00. However, because of daylight tine saving I get values from 1:00:00 after March 12.
Am I missing any time configuration in the project?
Perspective defaults the timezone to the client's set timezone. If you want to display UTC or no daylights saving you should set the 'Project Timzone' to your desired TZ.
This can get confusing when you have any datetime entry in your project though, as the perspective project will take the time as the set timezone. So a user would have to know this when entering data.
For this instance, I would keep what you have and just note DLS for the chart.
