How To Add Milliseconds To Current Time In Mysql

None of us tin dispute that time is a critical factor both in computing and the real globe. It allows us to create records of when an activity takes place.

In this tutorial, we will look at how to insert date and time records in a database. This can include when we added a specific record to the database.

MySQL now() Function

The simplest method to insert the electric current date and fourth dimension in MySQL is to use the now() function. Once y'all call the function, it returns the current engagement and time in the system's configured fourth dimension zone as a string.

The value returned from the now() part is YYYY-MM-DD for the appointment and HH-MM-SS-UU for the time record.

A simple utilise case of the now() function is:

Once we run the above query, nosotros should go the exact date and time when the query starts executing.

It is good to note that the now() part returns the date and fourth dimension when the query starts executing. If yous want the exact date and time the query completes, y'all can utilise the sysdate() role.

Example:

select sysdate ( ) ;
+---------------------+
| sysdate ( ) |
+---------------------+
| 2021 - 07 - 26 22:12:nineteen |
+---------------------+

This returns the current arrangement date and time when the query executes.

MySQL current_date()

If you want to go the electric current date just without including the time, y'all can use the curdate() role.

This function also returns the date in the grade of YYYY-MM-DD as a string. For case:

MySQL curtime() Office

Similarly, if y'all want to get the current fourth dimension without including the engagement, yous can use the curtime() function.

Here is an example:

The current engagement and time depend on the set time zone. To change the fourth dimension zone in MySQL, apply the Fix query as:

The in a higher place query should modify your time zone to your preferred option.

Loading MySQL Time Zones

In some instances, when you execute the above command, especially on Windows devices, you will get an "Unknown or Incorrect Fourth dimension Zone" fault.

The main crusade of this is the base organisation is not being populated with the time zones database.

To set up this, you can load the fourth dimension zones database as described in the following steps:

CAUTION: Do NOT use this method on a organisation that comes with zoneinfo files loaded. For case, in Linux, the zoneinfo files are loaded in /usr/share/zoneinfo directory:

Footstep i: Open your browser and navigate to the MySQL timezones download page:

https://dev.mysql.com/downloads/timezones.html

Step 2: Next, download the timezone archive file for your MySQL version. If yous are using MySQL five.6 and below, download the Posix standard equally Windows is POSIX compliant:

Footstep 3: Once yous have the fourth dimension zones parcel downloaded, open a command session and navigate to the location of the time zone file:

cd C:\users\linuxhint\Desktop

Stride four: Finally, use the command below to load the time zone file:

mysql_tzinfo_to_sql timezone_2021a_posix_sql.zero | mysql -u root -p

Replace the time zone zip file with the name of the downloaded file.

If you complete the above control merely withal get an error, excerpt the annal above to get the timezones_posix.sql file.

Next, use MySQL to load the time zones using the command:

mysql -u root -p -D mysql < timezone_posix.sql

The in a higher place two steps should resolve the error and let you to modify the time zones for the MySQL server.

For case, to set the time zone to New York, use the command:

SET time_zone = 'America/New_York' ;

Once executed successfully, you can now call the at present() function to get the fourth dimension based on your gear up time zone.

select now ( ) ;
+---------------------+
| now ( ) |
+---------------------+
| 2021 - 07 - 26 15:48:49 |
+---------------------+

Note: There are more options to configure MySQL fourth dimension zones than the one discussed in this tutorial. Check out the documentation to learn more.
