But that is the userid of the person who created the Feed is it not?
How does that relate to the current user or a public dashboard? The Feed could be created by a user in a different timezone to the feed itself.
I wonder if a Feed needs a timezone attribute. Might solve a whole host of other issues with viewing data such as a ‘day’ of data relating to that feed. You could then workout when midnight was for each feed.
Is it not the case that, when viewing data, it should always relate to the local time that data was collected?
