If this data is not entered correctly the system is unable to discern the infix as valid data. This is frequently the case with time and date fields. In this situation an error handling theodolite is needed, users will perriodically make input errors. Design considerations are much focused on the wrong issues, to much time is faded 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 can understand e xactly how they should enter the data. Howev! er, level this does not always help, users still make input errors, and developers complain about their stupid users.
