Suppose we wish to keep history and trends forever. In that case, we wish to enter the maximum value into "Keep history" and "Keep trends" fields in item configuration. However, it is unclear what the maximum value is.
It turns out that the maximum value is 65535 days (by the way, why?), but it would be nice if the GUI would help the user to find that value. Currently, it allows to enter an eight digit number into both fields and then complains:
- Warning. Incorrect value for [history]
- Warning. Incorrect value for [trends]
