Here is a screenshot showing the tab at 250h interval.

My suggestion would be to change the intervals to be 1 day = 1 unit. Though I'm not sure if this is intentional, I just don't think it feels right. Specially since every other interval lower than 250h uses a nice unit like seconds, minutes and hours.
Just a last reminder, every tab (not just production, the fluids, buildings and pollution) also have these weird intervals.
