      • DateTime (without time zone)

      Introduction

      In NocoBase, DateTime (without time zone) stores a local date and time without time-zone conversion.

      It is suitable for local schedules, business hours, and values that must remain unchanged as entered. Use DateTime when the same instant must be interpreted consistently across time zones.

      Use cases

      DateTime (without time zone) fields are suitable for these business scenarios:

      • Local schedules and business hours
      • Local appointment times
      • Store opening and closing times with a date
      • Time values imported without time-zone data

      Create and configure

      On the collection's Configure fields page, click Add field and select DateTime (without time zone) to create this field.

      Configure a DateTime (without time zone) field

      SettingDescription
      Field interfaceThe field interface. DateTime (without time zone) uses datetimeNoTz, which determines how the field is entered and displayed in pages.
      Field display nameThe name displayed for the field, such as Local schedule, Business time, or Appointment time. Use a name that business users can recognize.
      Field nameThe field identifier used internally by APIs, relation fields, permissions, and workflows. It usually cannot be changed after creation. It supports only letters, numbers, and underscores, and must begin with a letter.
      Field typeThe data-layer type. DateTime (without time zone) uses datetimeNoTz by default.
      Default valueThe default value. When a new record has no value, NocoBase can fill this value automatically.
      Validation rulesValidation rules. Supports date-range and required validation.
      DescriptionA field description. Record the field meaning, entry requirements, data source, or maintainer.
      Note

      Field names are referenced by page blocks, permissions, workflows, and APIs after creation. Confirm the name before creating the field to avoid later configuration changes.

      Field behavior

      The default behavior of a DateTime (without time zone) field is as follows:

      BehaviorDescription
      Default Field interfacedatetimeNoTz.
      Default Field typedatetimeNoTz.
      Available Field typesdatetimeNoTz.
      Page componentUses a date-time picker in edit mode.
      FilteringSupports date-time filters such as before, after, range, is empty, and is not empty.
      SortingSupports chronological sorting in Table blocks.
      ValidationSupports date-range and required validation.

      Edit configuration

      After creation, click Edit beside the field to edit its configuration. Edit fields to adjust how they are displayed and used in NocoBase, such as the display name, description, default value, validation rules, or field-specific settings.

      When a field comes from a synchronized main-database table, editing usually maps the database field to a NocoBase Field type and Field interface.

      SettingCan be editedDescription
      Field display nameYesChanges the name displayed in the interface without changing the field identifier.
      Field nameNoThe field identifier normally cannot be changed in the edit form after creation.
      Field interfaceConditionalMain-database fields and synchronized fields can be adjusted during field mapping. Changes affect page input, display, and validation.
      Field typeConditionalMain-database fields and synchronized fields can be adjusted during field mapping. Confirm that existing values can be used by the new type first.
      Default valueYesAdjusts the default value for new records.
      Validation rulesYesAdjusts field validation rules.
      DescriptionYesAdds the field meaning, entry requirements, data source, or maintainer.
      Note

      Changing a Field type or Field interface is more than changing a display name. It affects field storage, input components, validation rules, filters, and workflow-variable usage. When the field contains substantial existing data, confirm that its data format is compatible first.

      Delete field

      Click Delete beside a DateTime (without time zone) field to delete it. You can also select multiple fields and delete them in the main data source.

      Deleting a DateTime (without time zone) field created in the main database usually also deletes the actual database column and its values. For a synchronized or external-data-source field, the impact depends on the corresponding data source and field origin.

      Warning

      Deleting a field can affect page blocks, forms, filters, permissions, workflows, APIs, imports and exports, and existing data. Confirm that the field is no longer referenced by business configuration before deleting it.

      Use in pages

      DateTime (without time zone) fields are suitable for local schedules and business time values.
