How Do You Write a TIMESTAMP for Data Type?


Angela Bailey

When working with databases, it is essential to understand how to handle different data types. One commonly used data type is the TIMESTAMP. In this tutorial, we will learn how to write a TIMESTAMP for a data type using HTML.

What is a TIMESTAMP?

A TIMESTAMP is a data type that stores date and time information. It represents a unique point in time, typically recorded as the number of seconds or milliseconds since the Unix epoch (January 1, 1970).


To write a TIMESTAMP in HTML, we can use the <time> element, which is specifically designed for representing dates and times.

The <time> element has an attribute called datetime, where we can specify the timestamp value. The format for the datetime attribute is YYYY-MM-DDThh:mm:ss (year-month-day T hour:minute:second).

Let’s look at an example:

    The event took place on <time datetime="2022-07-15T10:30:00">July 15th, 2022 at 10:30 AM</time>.

In this example, we have used the <time> element to display a specific event’s timestamp. The datetime attribute specifies the exact date and time when the event occurred.

Displaying Formatted Timestamps

The default rendering of the <time> element depends on the user agent/browser. However, you can provide additional information by using the <datetime> attribute and formatting the timestamp using JavaScript or CSS.

For example, we can use JavaScript to format the timestamp into a more human-readable format:

    The event took place on <time datetime="2022-07-15T10:30:00" id="event-time"></time>.

    const eventTime = document.getElementById('event-time');
    const formattedTime = new Date(eventTime.getAttribute('datetime')).toLocaleString();
    eventTime.textContent = formattedTime;

In this example, we have added an empty <time> element with an id of “event-time.” We then use JavaScript to retrieve the datetime attribute value, convert it into a human-readable format using toLocaleString(), and display it inside the <time> element.


The <time> element in HTML provides a simple and semantic way to represent timestamps. By using the datetime attribute, we can specify the exact date and time for a given event. Additionally, with JavaScript or CSS, we can format and display the timestamp in a more readable format.

Now that you understand how to write a TIMESTAMP for a data type using HTML, you can confidently handle date and time information in your web applications.
