![]() The value of the last modified time will change if you add or remove a record from a linked record field, but it will not change if the fields associated with the linked record(s) have been changed-for example, changing the primary field of the linked record or any other fields that live in another table will not update the value of last modified time. To designate a specific field, reference the field name within the parentheses like this: LAST_MODIFIED_TIME() To output the last modified time of the entire record, just write LAST_MODIFIED_TIME() in the formula field. When used as a formula function, LAST_MODIFIED_TIME() can be customized to make the same selection within the formula itself. When used as a field, the Last modified time provides a visual selector to choose whether to display the time either the record or a specific field was modified. Similar to created time, the last modified time function exists both as a field type and as a formula function. Last modified time: another field and formula combo "This record was created on " & DATETIME_FORMAT(CREATED_TIME(), "D/M/YY") To make this type of formula more readable for humans consider formatting the datetime with a formula like this: The datetime is in ISO format, which works well when a machine is reading it. However, when you combine an output of plain text with a computed date function, you'll get the result below: Let's say you wanted to display a message along with the created time of a record, something like "This record was created at CREATED_TIME()." To output that, you would write this formula: "This record was created on " & CREATED_TIME(). You can find a lot more information on working with dates in other articles, but let’s take a look at a short example to familiarize you with the process. If you want to use created time in conjunction with other text, you'll need to wrap the function with some date formatting in order for it to display properly. Note that since the created time for a record will always be the same, there is no way to directly edit the contents of the cells in the created time field (just like other computed fields!). This may be one of the most straightforward formulas we have, as there are no other functions to add or adjust.Īs with the date field, you can customize the date format, choose to include a time stamp, and choose whether to use the same time zone for all collaborators. When used as a formula, created time can simply be entered as CREATED_TIME(). ![]() “Created time” is a field type that will automatically show the date (and optionally, time) that a record was created-and it's also a formula! This article is part of a guided course which you can view here. ![]() This article will cover the basics of how they work, while the next article will dive in a bit deeper into different ways to leverage them. This article is part of a guided course that helps you learn how to use Airtable formulas.There are several formula functions that can be used to return data about individual records. You can use a formula like the following to output the character count of the text field: LEN ()) will convert the arrayed results on the lookup into a readable string, and then return the length of that string. Let's say that you have a base setup to track social media content, and want to make sure your tweets don't exceed the 280 character limit. You can reference a value / field / string within the function following this format: LEN(string).Ī popular use for this function is determining word and character counts in order to alert you if you've ran over a specified limit (think character counts for tweets, word counts for blog articles). ![]() This is a very straightforward function that simply returns the length of a string. ![]() There are four different functions that can help you do that: This article will cover how to extract specified values (and amounts) from fields. ![]()
