What Is the Data Type of Timestamp?

When working with databases or programming languages, you may come across the term “timestamp.” But what exactly is a timestamp and what data type does it belong to? Let’s dive into this topic to gain a better understanding.

Definition of Timestamp

A timestamp is a value that represents a specific point in time. It is commonly used to track when a particular event occurs or to record the creation or modification time of records in a database. In simple terms, it tells us when something happened.

Data Type of Timestamp

In most programming languages and databases, the data type for timestamps is called datetime. This data type allows you to store both date and time information together. It provides a way to perform various operations on dates and times, such as calculating differences between two timestamps or formatting them in different ways.


datetime myTimestamp = 2022-01-01 14:30:00;

Working with Timestamps

Once you have a timestamp stored in your database or programming language, you can perform several operations on it. Some common operations include:

  • Comparing timestamps: You can compare two timestamps to check if one occurred before, after, or at the same time as another.
  • Calculating differences: You can calculate the difference between two timestamps in terms of seconds, minutes, hours, days, etc.
  • Formatting timestamps: You can format timestamps according to your desired display format using functions provided by your programming language or database.

Timestamps in Different Databases and Programming Languages

While the concept of timestamps remains the same across different systems, the syntax and functions to work with them may vary. Here are a few examples:

  • MySQL: In MySQL, you can use the DATETIME data type to store timestamps. MySQL provides various built-in functions like NOW() to get the current timestamp.
  • PostgreSQL: In PostgreSQL, you can use the TIMESTAMP data type for timestamps.

    PostgreSQL offers many date and time functions like CURRENT_TIMESTAMP to retrieve the current timestamp.

  • Python: In Python, you can work with timestamps using the datetime module. This module provides classes and functions to manipulate dates and times conveniently.

In Conclusion

A timestamp is a valuable piece of information that helps us track events or record creation/modification times. It belongs to the data type called datetime in most programming languages and databases. Understanding how to work with timestamps allows us to perform various operations and extract meaningful insights from our data.

In this article, we explored what a timestamp is, its data type, common operations on timestamps, and examples from different databases and programming languages. Armed with this knowledge, you’ll be well-equipped to handle timestamps effectively in your projects.
