Datetime Fields

Using Application Composer, you can extend an application's object model by adding new fields to both standard or custom objects.

One such field type is datetime, where users in the runtime application can enter a date or select one from a calendar, and enter a time of day.

Datetime Field Properties

Create a datetime field by specifying values for the common set of field properties, such as display label and field name. You also set properties for this field that are specific to the datetime field type.

The following table shows properties that are common across multiple field types:

Field Property	Field Property Region
Label	Appearance
Help Text	Appearance
Name	Name
Description	Name
Required	Constraints
Updatable	Constraints
Searchable	Constraints
Indexed	Constraints
Fixed Value	Default Value Note: When you select a literal date for this field's default value, the selected date appears in the international standard notation for date and time of day; however, at runtime, the date and time of day are displayed according to the user's preferences.
Expression	Default Value
