The control field can be used to set a date field not to show the time.

Go to Menu, Setup > Field Headings > All Fields (Global).

Note that selecting the Global option will amend the format for all areas.

If you only wish to amend the settings for a specific area ensure you are in that Database Area and select Menu, Setup > Field Heading > All Fields (Area: XXX)

Find the date field in the list that you wish to amend, in the control field enter the following value:

*dateonly

Changes are saved automatically when you click out of the text field.

You can also use the *dateonly control when adding the field to a Panel. Simply add the text to the control field in the popup when creating your field.
