I am creating a time reporting tool. Users will use this web app to enter and record the time they spend on an activity (task). Users can add time in hh:mm format. Users can also enter values in decimal, which will be converted into hh:mm format by the system.
For example: when user enters 3.5, it converts into 3:30. or 3.25 into 3:15 or 3.10 into 3:06 This conversion is done by the system. For the user to notice these changes made by the system, I want to add a feedback message. I am not sure what kind of feedback message would make sense. Please refer to attached images.
Any help is appreciated.
