Datetime vs Timestamp – Basic Differences Laravel

While working with Laravel, one of the most common snippet you’ll see is managing dates and times. you’re building an application that tracks events, logs user activity, or schedules tasks, You need to understand how to handle date and time data that is very difficult. There are two of the primary ways to manage this data in Laravel are through Datetime and Timestamp fields. Here in this blog we will explain you the differences between Datetime and Timestamp. which significantly add more features to your website.

Datetime in Laravel

Datetime in Laravel mention to a particular date and time. It is stored in the format YYYY-MM-DD HH:MM:SS and this is widely used to save current time in particular format. This format is very readable and easy to understand.

Datetime fields can be used in specific cases like where you need to capture actual moments. For example, logging when a user last logged in, when a blog post was published, or when an order was placed.

$table->datetime('published_at');

• timestamp stores time in seconds, and datetime stores it in a specific format (usually YYYY-MM-DD HH:MM:SS)
• timestamp has a range of 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07 UTC, while datetime has a range of 1000-01-01 00:00:00 to 9999-12-31 23:59:59, giving you a much wider range of dates. – source
• timestamp is stored in 4 bytes, while datetime is stored in 8 bytes, which means that timestamp takes up less space
• timestamp is stored in UTC, while datetime is stored in the timezone of the server
• datetime can support fractions of a second, while timestamp cannot

So, which one should you use? It depends on your use case. If you need to store dates between 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07 UTC, then you should use timestamp. This will make the date searchable really quickly.

But if you need to store dates outside of that range, then you should use datetime. Or if you need to have a timezone other than UTC, then you should use datetime.

Timestamp in Laravel

A Timestamp in Laravel is a numeric representation of a specific moment in time, typically expressed as the number of seconds since January 1, 1970. It is stored as an integer, making it highly efficient for storage and comparison.

Timestamps are particularly useful for logging events or actions where the exact time is critical but the format is less important. For example, recording when a record was created or updated.

$table->timestamp('created_at');
$table->timestamp('updated_at');

Key Differences Between Datetime and Timestamp

Storage Format

Datetime is stored in a YYYY-MM-DD HH:MM:SS format, which is easy to read but takes more space. Timestamp is stored as an integer, which is more compact and efficient.

Both Datetime and Timestamp offer similar levels of precision, but Timestamps can handle microseconds if needed

Datetime can include time zone information directly, whereas Timestamps are typically stored as UTC and converted as needed.

$table->datetime('appointment_at');

When to Use Timestamp

Timestamp is ideal for logging events or actions where efficiency and storage space are priorities. It’s commonly used for tracking record creation and updates.

Practical Examples in Laravel Applications

$table->timestamp('created_at')->useCurrent();

Conversion Between Datetime and Timestamp

Methods and Functions in Laravel

Laravel provides methods to convert between Datetime and Timestamp. For instance, you can use Carbon to handle conversions easily.

$datetime = '2023-07-28 12:34:56';
$timestamp = strtotime($datetime);

$timestamp = 1690557296;
$datetime = date('Y-m-d H:i:s', $timestamp);

Handling Time Zones in Laravel

Time zones are crucial for global applications to ensure times are accurate across different regions.

How Laravel Manages Time Zones with Datetime and Timestamp

Laravel can handle time zones using the Carbon library, making it easy to convert between time zones.

$datetime = Carbon::now('Kolkata/India');
$datetime->setTimezone('GMT+5:30');

Testing Datetime and Timestamp in Laravel

Ensure your tests cover edge cases, such as daylight saving changes and time zone conversions.

Use Laravel’s built-in testing tools and the Carbon library for mocking dates and times.

use Carbon\Carbon;

Carbon::setTestNow(Carbon::parse('2023-07-28'));
