One really useful function of many of the multi-choice tools in the form builder toolbox is the ability to set default values. Defaulting the calendar tool to today’s date is often really useful for mobile users.
In the form-field properties of the calendar tool a min/max date can be chosen, particularly relevant when the form will only be used for a certain period of time say, a week, and the initial value can set to the first day of the week.
Date When building your form, in the Form-field properties of the Calendar tool, enter into the Formula box: =today()
Time The Time tool will capture a specific time of day in hours and minutes. Reduce errors and get more accurate data by using the formula: =now()
