# Formula - date / time field properties

The properties for this field type are:

## Label

Enter a name for this field. This name displays on data-entry forms and as column headings in reports.

## Type

Select **Change Type** to change the field type.

Some field types (List-User, Multi-select Text, and File Attachment, for example) may not be changed. The **Change Type** link will not be present if this is the case.

## Unique

| Select this option... | If you want to... |
| --- | --- |
| Must be unique | Ensure that every entry in this field is different. This is useful for fields that contain information such as product serial numbers or ID numbers. |
| Check existing entries for duplicate values | Change a field in an existing application to require unique values and want to require that all previously entered data is unique. To display this option, select **Must be unique**. If Quickbase finds existing values in this field that aren't unique, an error message appears and Quickbase clears the **Must be unique** checkbox. If this occurs, you can do one of two things: - Sort the field to find duplicate values, make corrections as necessary, return to the Properties page, then select both **Unique** checkboxes again. - Select **Must be unique** if it doesn't matter whether existing data in this field is unique or if you want only new entries in this field to be unique. |

## Formula

Enter the formula to generate the value this field shows. When you select the **Formula** text field, a **Fields & Functions** list appears.

1. Select **Select a Function** to open the Quickbase Formula Functions dialog box.
2. Select or search for the type of function you want from the list.
3. Select the formula you want, then select **Insert**.

## Format

Quickbase date and time fields display in the following format: 07-08-2012 03:45 PM. To format the date differently, select one or more of the following checkboxes:

| Select this option... | To display... |
| --- | --- |
| Show the month as a name | The first three letters of the name of the month. For example, JUL-08-2012. |
| Show the day of the week | The day of the week and the date. For example, Sunday, 07-08-2012. |
| Don't show the year for dates in the current year | The date using commas, for example, 07, 08, 2012. If the date falls within the current year, Quickbase does not display the year. For example, if you enter 07-08-2012, and the current day falls within 2012, the date that appears is 07 08. Tip: Select Show the month as a name to display the date as Jul 08, 2012. |
| Show the time | The time and the date. For example, 07-08-2012 03:45 PM. Note: Quickbase turns on this option automatically. It's the default. |
| Show the time zone | The time zone after the date and time. For example, 07-08-2012 03:45 PM (PST). |

### Value display

These properties apply when the field appears in table and timeline reports.

| Select one or more options... | To... |
| --- | --- |
| Display in bold | Display the data in bold. |
| Display without wrapping | Prevent the data from being broken into multiple lines. |
