If this data is not entered correctly the system is unable to cathexis the excitant as valid data. This is frequently the case with time and date fields. In this situation an error handling transition is needed, users will perriodically make input errors. Design considerations are a great deal focused on the wrong issues, to much time is watery on formulating the desired error message and where it must be displayed in the process.
Frequently system programmers will design a system that provides instructions built into the application, therefore providing the correct input format. So the users c an understand exactly how they should enter ! the data. However, til now this does not always help, users still make input errors, and developers chitchat about their stupid users.
