When you select Date and Time Text Fields in Configure/Color Data View, this will display the data and time stamp recorded with every measurement at the time it was taken.
You can change the Date format in Options à Application Preference à Units.
Unlike the date, EasyMatch QC does not allow you to change the time format from within the package but instead uses whatever format is configured for Windows. To change the Time format, go to Start à Control Panel à Regional and Language Settings where you can set the time to 24 Hour format (or other formats) which will in turn display that way in EasyMatch QC.
