The LOCALTIME SQL Function in MySQL and MariaDB - Local date and time

LOCALTIME	Syntax:	LOCALTIME([Precision])
	Return value:	DATETIME
	Synonyms:	LOCALTIMESTAMP, NOW, CURRENT_TIMESTAMP
	Function type:	Date and Time function

Function Description

The LOCALTIME() function returns the current date and time as a string YYYY-MM-DD hh:mm:ss or numerically as BIGINT YYYYMMDDhhmmss or as DECIMAL YYYYMMDDhhmmss.microseconds, depending on whether the function is used in string or numeric context.

The value is expressed in the format of the current session time zone.

The "Precision" argument can be specified to indicate a sub-second precision from 0 to 6 digits.

The specification of "Precision" must be a written number from 0-6. Expressions or variables produce a syntax error, larger values produce a precision error.

Unlike the NOW() function, this function can omit the parentheses if "Precision" is not specified.

Setting the system variable timestamp takes affect to the function LOCALTIME() in contrast to then SYSDATE() function.

SQL Examples for the LOCALTIME function


SELECT localtime(), localtime() + 1, localtime() + 0.001;
SELECT localtime(6), localtime(6) + 1, localtime(6) + 0.001;
SELECT localtime;

SELECT localtime(7);
SELECT localtime(3 + 2);
SET @a=3;
SELECT localtime(@a);

select localtime(3 + 2)

errno: 1064 sqlstate: 42000 error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '+ 2)' at line 1

select localtime(@a)

errno: 1064 sqlstate: 42000 error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '@a)' at line 1

Examples of how setting the system variable timestamp affects


select now(), SYSDATE();
set session timestamp = UNIX_TIMESTAMP()+1000;
select now(), current_timestamp(), localtime(), sysdate();

How to use the LOCALTIME() function in MySQL and MariaDB databases

In MySQL and MariaDB the LOCALTIME() function is used to get the current date and time. The function returns the current timestamp in the format "YYYY-MM-DD HH:MM:SS". LOCALTIME() can be used to get current date and time in SQL queries, as default value for timestamp columns in tables, in timezone consideration or in various calculations or manipulations with timestamps using functions that add or subtract time intervals from the current timestamp value.
