I’ve run into this, too. Just recently in 2022.5 something changed and now some of my dashboard displays which were in decimal hours are in HH:MM:SS format. That’s OK, but I don’t need the seconds to display. It only makes the screen look cluttered.
In hopes of avoiding the flood of responses I know would come, let me be clear: I know I can create a template in whatever format I want. I’ve got dozens of templates already. I don’t think it’s a good practice to create templates (data) simply to display a value. The display should be separate from the data.
This isn’t the first time this has come up. A quick search came up with this question, and a few Feature Requests. I suggest up-voting any you agree with:
There are no doubt more discussions on this; I just did a very quick search.
