Can you please respond on the following report of a critical bug:
https://www.thecoderscorner.com/jforum/posts/list/95.page. We have tried to recreate this scenario both on the in-development version, and the production 1.7 version, we cannot recreate it, getCurrentValue always returns the right value. If you are still able to recreate this issue, please provide the library versions, board version from board manager, and the board that you are using.
In terms of the issue, it is more than possible, but it's not trivial, if you are used to C++ programming you could. Another option without waiting is to use a regular text field and format it yourself. However, we were thinking of adding duration anyway, so we could add this at the same time. Please feel free to comment on
